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

Jun 28, 2016

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) :)

$\sqrt{4}$ = 2 (2 x 2 = $4$)

$\sqrt{{a}^{2}}$ = a (a x a = ${a}^{2}$)

$\therefore$ the square root of $4 {a}^{2}$ is 2a
