9 * (7 - 4)^2 +9

I think it is
9 *(3) ^2 +9
9 x 9 + 9 =81
I hope I got this right. I am trying

Your method is correct, but your last line is wrong.

9 x 9 + 9 =81

Do I leave the last line off or change it 9x9+9=9

I mean 90 I think I should leave it off because expression do not have a = right

90 is correct.

Thanks for the help and I believe this is as simplified as I know. If there is something I am missing please tell me.

Yes, you got it right! Let me break down the steps for you to verify your answer.

The given expression is 9 * (7 - 4)^2 + 9. To solve it, follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, Addition and Subtraction from left to right).

Step 1: Evaluate the expression within the parentheses first: 7 - 4 = 3.

Now the expression becomes: 9 * 3^2 + 9.

Step 2: Evaluate the exponent: 3^2 = 3 * 3 = 9.

Now the expression becomes: 9 * 9 + 9.

Step 3: Perform multiplication: 9 * 9 = 81.

Now the expression becomes: 81 + 9.

Step 4: Perform addition: 81 + 9 = 90.

Therefore, the final answer is indeed 90, just as you calculated. Well done!
