Question

How do you solve `m^2=11`?

Answer 1

`m=+-sqrt11`

Explanation:

Square roots are canceled out by squaring.
Like this...

`m^2=11`

Square both sides to get rid of the square root.
Remember when you cancel a square using square root it is positive and negative.

`sqrt(m^2)=+-sqrt11`

`sqrt(m^color(red)cancel2)=+-sqrt11`

`m=+-sqrt11`
