Frequently asked questions on the topic of Maths
Q: Work out (5+√3)(5-√3) and give your answer in its simplest form.
A: The answer is 22. Rationalise the denominator of 1/√3. The expansion of (2+√3)(1+√3) is 18+2√5.
Q: Rationalise the denominator of √3/√3 and -√3/53. Also, expand and simplify (√3+ √15)².
A: The rationalisation of √3/√3 and -√3/53 is 1 and -√3/53 respectively. The expansion and simplification of (√3+ √15)² is 18+2√45.
Q: Expand and simplify (√3-√2)(√3-√2) and find the value of 49¹/2. Also, write √45 in the form k√5.
A: The expansion and simplification of (√3-√2)(√3-√2) is 3√5. The value of 49¹/2 is 7 and √45 can be written as 3√5.
Q: Expand and simplify x(x + 1)(x - 1) and prove that n³-n is a multiple of 6 for all possible values of n.
A: The expansion and simplification of x(x + 1)(x - 1) is x(x² - 1). The proof that n³-n is a multiple of 6 is true for all possible values of n.
Q: Prove algebraically that (2n + 1)² (2n + 1) is an even number for all positive integer values of n and factorise x² + 7x.
A: The algebraic proof that (2n + 1)² (2n + 1) is an even number for all positive integer values of n is true. The factorisation of x² + 7x is x(x + 7).
