Question

8^2 + 9(12 ÷ 3 × 2) - 7 solve in steps

Answer 1

= 8x2+ 24 -7
= 16 + 24 -7
=16 +17
= 33

Answer 2

75.

Start with the stuff in parentheses:

12÷3×2.

3×2=6

12÷6=2.

Then we move to the exponents.

8²=64

Then we move to the 9 and multiply that by 2.

9×2=18

and then that leaves us to subtract 7.  Our equation now looks like

64+18-7=75.
