OpenStudy (anonymous):

explain how to solve 8 exponet 2 + 9(12 ÷ 3 • 2) – 7

OpenStudy (anonymous):

Is 129 one of your choices?

OpenStudy (anonymous):

use PEMDAS

OpenStudy (anonymous):

there is no choices

OpenStudy (anonymous):

i tried but im confused

OpenStudy (anonymous):

First do (12/3*2)

OpenStudy (anonymous):

8

OpenStudy (anonymous):

Then do 8^2 which is 8*8

OpenStudy (anonymous):

64

OpenStudy (anonymous):

Pemdas is parentheses, exponents, multiplication, division, addition, and subtraction. Do it is that order and there's your answer

OpenStudy (anonymous):

so do i add 64 to 9 next

OpenStudy (anonymous):

After you did 12/3*2 you got 8 Then you did 8^2 and got 64 After that you multiply 9*8

OpenStudy (anonymous):

which gives my 72

OpenStudy (anonymous):

Since we have no division problem, you skip that step and go to addition. Add 64+72

OpenStudy (anonymous):

136

OpenStudy (anonymous):

Now subtract 7

OpenStudy (anonymous):

129

OpenStudy (anonymous):

There's your answer

OpenStudy (anonymous):

thanks so much
