Question

I need help please?!!!

Answer 1

Explanation:

`\bigg( \frac{ {7}^( - 3) }{10} \bigg)^( - 2) \\ \\ = \bigg( \frac{ 10}{{7}^( - 3) } \bigg)^( 2) \\ \\ = \bigg( { 10 *{7}^( 3) } \bigg)^( 2) \\ \\ = \bigg( { 10^( 2) *{7}^( 3 * 2) } \bigg) \\ \\ = {7}^( 6) * 10^( 2)`

Answer 2

Explanation:

`((7^(-3))/(10))^(-2)=\frac{7^({-3*-2})}{10^(-2)}\\\\=(7^(6))/(10^(-2))\\\\=7^(6)*10^(2)`

`(a^(m))^(n)=a^(m*n)\\\\(1)/(a^(-m))=a^(m)`
