The Laws of Indices (Junior Cert Mathematics): Flashcards

How many times to multiply a number by itself

$2$

$3$

$a^p \times a^q = a^{p+q}$

Add the powers

$\frac{a^p}{a^q} = a^{p-q}$

Subtract the powers

$(a^p)^q = a^{p \times q}$

Multiply the powers together

The base

Take the reciprocal, then apply the positive power
