Mathematics

The value of z is 3.

Step-by-step explanation:

You have to use Indices Law,

${( {a}^{m}) }^{n} \: ⇒ \: {a}^{mn}$

So for this question, first you have to get rid of brackets :

${ ({q}^{4} )}^{z} = {q}^{12}$

${q}^{4z} = {q}^{12}$

Next you can solve it since both have the same bases :

${q}^{4z} = {q}^{12}$

4z = 12

z = 3
