Answer 2

$\displaystyle \sf{ { \bigg[ {( - 3)}^{2} \bigg]}^{3} } = 729$

Given :

$\displaystyle \sf{ { \bigg[ {( - 3)}^{2} \bigg]}^{3} }$

To find :

The value of the expression

Solution :

Process : 1

Step 1 of 2 :

Write down the given expression

The given expression is

$\displaystyle \sf{ { \bigg[ {( - 3)}^{2} \bigg]}^{3} }$

Step 2 of 2 :

Find the value of the expression

We use the formula

$\displaystyle \sf{ {( {a}^{m} )}^{n} = {a}^{mn} }$

Thus we get

$\displaystyle \sf{ { \bigg[ {( - 3)}^{2} \bigg]}^{3} }$

$\displaystyle \sf{ = {( - 3)}^{2 \times 3} }$

$\displaystyle \sf{ = {( - 3)}^{6} }$

$\displaystyle \sf{ = 729}$

Process : 2

Step 1 of 2 :

Write down the given expression

The given expression is

$\displaystyle \sf{ { \bigg[ {( - 3)}^{2} \bigg]}^{3} }$

Step 2 of 2 :

Simplify the given expression

$\displaystyle \sf{ { \bigg[ {( - 3)}^{2} \bigg]}^{3} }$

$\displaystyle \sf{ = { (9)}^{3} }$

$\displaystyle \sf{ =9 \times 9 \times 9}$

$\displaystyle \sf{ =729}$
