Question

How do you simplify `(5³)times (9-2) ÷ (2^4 ÷ 2²)` using PEMDAS?

Answer 1

`218.75`

Explanation:

The first thing to simplify are the terms inside the parenthesis. Inside the parenthesis, if there is only one operation, do that; if there are more than `1`, then follow the PEMDAS rule.

`(5^3) xx (9-2) -: (2^4-:2^2)`

`=125 xx 7 -: (16 -: 4)`

`=875 -: 4`

`=218.75`

Hope this helps!
