Simplify. 3^2+ (9-8/2)

solmaris [256]

Hi there! Hopefully this helps!

-----------------------------------------------------------------------------------------------------------

Answer: 14.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

First we calculate 3 to the power of 2 and get 9.

9 + 9 - $\frac{8}{2}$ = 14.

Now we add 9 + 9 to get 18.

18 - $\frac{8}{2}$ = 14.

Then, we divide 8 by 2 to get 4.

18 - 4 = 14.

Then we subtract 4 from 18 to get.....You guessed it, 14!
