Question

How do you simplify `(8- 4) ^ { 2} + 8\div 4`?

Answer 1

`18`

Explanation:

There are 2 terms. Each will simplify to a single answer which can be added or subtracted in the last step.

Within each term: brackets are done first, then powers and roots and then multiply and divide.

`(color(red)(8-4))^2 + color(blue)(8div4)`

`=color(red)((4)^2)color(blue)( +2)`

`= 16+2`

`=18`
