Simplify
11(9^ - 5^) / 2^ + 8)
My answer is 51.3
9^ means 9^.5 or 9^2 or 9^.7315 or what?
from your answer I am guessing 9^2
11 (81 - 25) /(12)
= 51 1/3 yes
I'm sorry about that but we have been told to use that symbol for a number being squared and I just use it out of habit.
Thank you for your help.

You are welcome :)
To simplify the given expression, we can follow the order of operations (PEMDAS/BODMAS) which states that we should first simplify within parentheses, then calculate any exponents, then perform multiplication and division from left to right, and finally, perform addition and subtraction from left to right.
Let's break down the given expression step by step:
1. In the given expression, we have a term within parentheses: (9^ - 5^). However, it seems there may be a mistake with the exponents. Exponents must have a base, and they should be separated from the base by either a multiplication sign or parentheses. Please double-check the exponents and provide the correct expression.
If you meant to write (9^2 - 5^2), then we can continue simplifying:
2. Simplify the exponents inside the parentheses:
9^2 = 9 * 9 = 81
5^2 = 5 * 5 = 25
The expression inside the parentheses becomes (81 - 25).
3. Perform the subtraction within the parentheses:
(81 - 25) = 56
4. Now, let's simplify the remaining expression:
11(56) / 2^ + 8
First, evaluate the term before the division sign:
11(56) = 616
Then, evaluate the term after the division sign:
2^ + 8 = 2 + 8 = 10
5. Finally, perform the division:
616 / 10 = 61.6
So, simplifying the given expression leads to the value of 61.6, not 51.3. Please check your calculations or provide the correct expression if I misunderstood the exponents.
