Simplify 6√72?

OpenStudy (blurbendy):

6Sqrt[72] = 6 * 6Sqrt[2] Do you follow so far?

OpenStudy (anonymous):

Uh, I think so. So I would multiply 6 by 6...? I think...

OpenStudy (blurbendy):

Yup!

OpenStudy (anonymous):

Oh, okay! Cool, thank you!

72 = 36·2 = 6²·2 So 6√72 = 6√(6²·2) = 6√6² ·√2 = 6·6√2 ···
