Question

How do you simplify `8 + 1/2 (4)^2 - 5` using PEMDAS?

Answer 1

`11`

Explanation:

First find the number of terms. In this case there are three.
Each term will simplify to a single answer. They will be added or subtracted in the last step.

`color(red)(8)color(blue)( + 1/2 (4)^2)color(magenta)( - 5)`

Do the most powerful operation first- powers and roots,

`color(red)(8)color(blue)( + 1/2 (16)color(magenta)( - 5)`

`color(red)(8)color(blue)(+8)color(magenta)( - 5)`

`=11`
