Answer 2

9514 1404 393

Answer:

1. simplify parentheses
2. evaluate the exponential term
3. divide 40/8
4. multiply 8*2
5. add 5+9
6. add 14+16

Explanation:

40/8+3^2+(15-7)*2 . . . . given

The order of operations tells you to start by evaluating expressions in parentheses. Here, that is the subtraction of 7 from 15.

40/8 +3^2 +8*2 . . . . (15-7) = 8

Then you evaluate exponential terms.

40/8 +9 +8*2 . . . . . 3^2 = 9

Then perform multiplication and division, left to right. Here, division is first, then multiplication.

5 +9 +8*2 . . . . . divide 40/8 = 5

5 +9 +16 . . . . . . multiply 8*2 = 16

Finally, perform addition and subtraction, left to right.

14 +16 . . . . add 5+9

30 . . . . . . . add 14+16
