Laws of indices - AQARaising a power to a power

Laws of indices give rules for simplifying calculations or expressions involving powers of the same base.

Raising a power to a power

Example

\((k^3)^2\).

This means that \(k^3\) is to be squared, or multiplied by \(k^3\) again: \((k^3)^2 = k^3 \times k^3\)

Add the powers together, so \((k^3)^2 = k^3 \times k^3 = k^6\), so \((k^3)^2\) can be simplified to \(k^6\).

Letters or numbers to the power of zero
