Question

4x2squared +9 \3-(8+3)

Answer 1

First thing you want to do is figure out the parenthesis. 8+3=11. So now we have:
4x2squared +9 \3-11

Now, the hard part about this is how you typed it. I am going to assume you typed it correctly. 9/3 is by itself the way you typed it. It is not:
(4x2squared +9) \(3-(8+3))

Where the 4x 2^2 + 9 is the numerator (number on top of the fraction) and 3-(8+3) is the denominator (number on the bottom). If that is the case, this will be done differently.

2^2 is 4. 9 divided by 3 is 3. So now we have:
4x4 + 3 -11

Start with multiplication.
4x4 = 16
So now it is:
16 + 3 - 11

What is your answer? :-)
