Question

How do you simplify `sqrt(4a^2)`?

Answer 1

2a

Explanation:

both variables are squares so you would just separate them and square them indivudally (but remembering to put them back together when you are done) :)

`sqrt4` = 2 (2 x 2 = `4`)

`sqrt(a^2)` = a (a x a = `a^2`)

`:.` the square root of `4a^2` is 2a
