Answer:

7

Explanation:

Lets use Pemdas for this

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

First you always do parenthesis, (47+4^2)

Then Exponents 4^2 this means 4x4 and 4x4=16

So (47+16)= 63

so we have 63/3^2

We go to exponents before division according to pemdas

3^2=3x3=9

63/9

63/9=7
