Answer:

\Huge \boxed{90}

Step-by-step explanation:

To solve this problem, first you have to use the order of operations stands for parenthesis, exponents, multiply, divide, add, and subtract numbers from left to right. Please Excuse My Dear Aunt Sally!

First, parenthesis.

(7-4)=3

9*3²+9

Next, exponent.

3²=3*3=9

9*9+9

Then, multiply numbers from left to right.

9*9=81

Add numbers from left to right.

81+9=90

Therefore, the correct answer is 90.

Answer:

90

Step-by-step explanation:

we have:

9*(7-4)^2+9

we subtract 7 and 4: 7-4

we have:

9*(3)^2+9

we know: 3^2=3*3=9

so we have:

9*9 +9

we multiply 9 by 9: 9*9 = 81, so we have:

81+9

90
