Worked Examples: Applying Index Laws

This page demonstrates practical applications of the laws of indices through worked examples. These examples illustrate how to use the laws to simplify complex expressions.

The first example shows:

m^4 × m^2 = m^6

This utilizes the addition law of indices, where exponents with the same base are added.

Another example presented is:

3r^3 × 5r^4 × 2r^8 = 30r^15

Example: In this case, we multiply the coefficients 3×5×2=303 × 5 × 2 = 30 and add the exponents of r 3+4+8=153 + 4 + 8 = 15.

These worked examples help reinforce the understanding of how to apply index laws in various scenarios, which is crucial for mastering algebraic manipulation.

Highlight: Practicing with diverse examples is key to becoming proficient in using index laws.

Advanced Index Law Applications

This page delves into more complex applications of the laws of indices, showcasing how they can be used to solve more intricate problems.

One of the examples presented is:

12n^10 ÷ n^2 = n^8

This demonstrates the subtraction law of indices, where exponents are subtracted when dividing terms with the same base.

Another example shown is:

15n^12 ÷ 3n^6 = 5n^6

Example: Here, we divide both the coefficients 15÷3=515 ÷ 3 = 5 and subtract the exponents 126=612 - 6 = 6.

These examples illustrate how index laws can be applied to simplify fractions and complex algebraic expressions.

Highlight: The ability to manipulate expressions using index laws is a crucial skill in advanced algebra and calculus.

Complex Index Manipulations

The final page presents more advanced applications of the laws of indices, demonstrating their use in complex mathematical expressions.

One example shown is:

m24m^24^9 = m^216

This utilizes the multiplication law of indices, where the exponents are multiplied when a power is raised to another power.

Another example is:

3r23r^2^4 = 81r^8

Example: In this case, we raise both the base number and the variable to the power of 4: 3^4 = 81 and r2r^2^4 = r^8.

These examples showcase how index laws can be applied to solve complex problems involving nested exponents and multiple variables.

Highlight: Mastering these complex manipulations is essential for success in higher-level mathematics courses.

The page also includes additional examples that further reinforce the application of various index laws in different scenarios.

Index Laws: Addition and Multiplication

The first page introduces two fundamental laws of indices: the addition law and the multiplication law. These laws are essential for simplifying expressions involving exponents.

Definition: Index laws are rules that govern how to manipulate expressions with exponents.

The page presents three key laws:

  1. Addition of powers: y^a × y^b = y^a+ba+b
  2. Subtraction of powers: y^a ÷ y^b = y^aba-b
  3. Multiplication of powers: yay^a^b = y^a×ba×b

Example: Using the addition law, we can simplify x^3 × x^4 to x^7 because 3 + 4 = 7.

These laws form the foundation for more complex operations with indices and are crucial for solving algebraic equations efficiently.

Highlight: The multiplication law of indices is particularly useful in simplifying nested exponents.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Samantha Klich

Android user

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Just amazing. Let's me revise 10x better, this app is a quick 10/10. I highly recommend it to anyone. I can watch and search for notes. I can save them in the subject folder. I can revise it any time when I come back. If you haven't tried this app, you're really missing out.

Basil

This app has made me feel so much more confident in my exam prep, not only through boosting my own self confidence through the features that allow you to connect with others and feel less alone, but also through the way the app itself is centred around making you feel better. It is easy to navigate, fun to use, and helpful to anyone struggling in absolutely any way.

David K

iOS user

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

In school I was really bad at maths but thanks to the app, I am doing better now. I am so grateful that you made the app.

Greenlight Bonnie

very reliable app to help and grow your ideas of Maths, English and other related topics in your works. please use this app if your struggling in areas, this app is key for that. wish I'd of done a review before. and it's also free so don't worry about that.

Rohan U

I know a lot of apps use fake accounts to boost their reviews but this app deserves it all. Originally I was getting 4 in my English exams and this time I got a grade 7. I didn’t even know about this app three days until the exam and it has helped A LOT. Please actually trust me and use it as I’m sure you too will see developments.

This apps acc the goat. I find revision so boring but this app makes it so easy to organize it all and then you can ask the freeeee ai to test yourself so good and you can easily upload your own stuff. highly recommend as someone taking mocks now
