Question

Use the properties of exponents to write an equivalent expression.

Answer 1

$\frac{ {12}^{6} }{ {12}^{2} }$
Here you subtract the exponent from the other
$\frac{ {12}^{6} }{ {12}^{2} } = {12}^{4}$

For the second one you multiply the exponents as so
$3 \times 5 = 15$
${ ({10}^{3} )}^{5} = {10}^{15}$
