Question

How to do order of operations with brackets `2[(9-8)^2+(12-5)^2]`?

Answer 1

`100`

Explanation:

This is all one term, but within thesquare bracket there are two terms which need to be simplified separately.

`2[color(red)((9-8))^2+ (color(blue)(12-5))^2]`

=`2[color(red)((1)^2)+ color(blue)((7)^2)]`

=`2[color(red)1+ color(blue)49]`

=`2 xx50`

=`100`
