Advanced Laws of Indices

This page delves into more complex applications of index laws, including negative and fractional indices.

The questions cover:

The law (a^b)^c = a^(bc)
Expressing 2^(p+q) in terms of x and y, given x = 2^p and y = 2^q
Expressing 2^(p-1) in terms of x and y, given x = 2^p and y = 2^q

Vocabulary: Negative indices indicate reciprocals. For example, a^(-n) = 1 / a^n

Example: (x^3)^-2 = x^(-6)

These questions help students develop a deeper understanding of index laws and their applications, preparing them for hard indices questions GCSE pdf.

Introduction to Laws of Indices

This page introduces the concept of indices and provides basic questions to familiarize students with the topic.

The first three questions cover fundamental concepts:

Calculating simple powers (2^6)
Understanding reciprocals
Evaluating a term when the power is 0

Definition: A reciprocal is the multiplicative inverse of a number. For example, the reciprocal of 2 is 1/2.

Example: 4^0 = 1 (Any number raised to the power of 0 equals 1)

These questions lay the groundwork for more complex indices GCSE questions and answers that follow.
