81

Explanation:

The order of operations is given by BIDMAS which stands for:
Brackets
Indices
Division
Multiplication
Addition
Subtraction

Deal with the brackets first:
${(7 + 2)}^{2} = 9^{2}$ $(7+2)^2=9^2$

Then the index:
$9^{2} = 81$ $9^2=81$

${(7 + 2)}^{2} = 81$ $(7+2)^2=81$

Explanation:

PEMDAS helps us to remember the order of operations when performing multiple operations in the same problem.

${(7 + 2)}^{2}$ $(7+2)^2$

According to PEMDAS, we need to first carry out the operation inside the parentheses, which is the addition of $7$ $7$ and $2$ $2$ .

${(7 + 2)}^{2} = {(9)}^{2}$ $(7+2)^2=(9)^2$

Next we apply the exponent $2$ $2$ and square the $9$ $9$ .

$9^{2} = 81$ $9^2=81$
