Question

Simplify:

sqrt 12

Answer 1

You've got to try do this by yourself now, or you will never learn to do it on a test mate. :)

Answer 2

hey it will be following:
sqrt 12 = sqrt ( 4 * 3)
sqrt 12 = sqrt4 * sqrt3
sqrt 12 = 2 * sqrt3 as sqrt4 = 2
sqrt 12 = 2sqrt3
HENCE \[\sqrt{12}\] = \[2\sqrt{3}\]
