Simplify: sqrt x^28x+16
I know that this can be factored out to sqrt (x4)(x4) what do i do next?

sqrt ( a*a) = a

Math  Shawn, Sunday, October 26, 2008 at 8:47pm
is it x4

Math  Damon, Sunday, October 26, 2008 at 8:48pm
Sure

Math  bobpursley, Sunday, October 26, 2008 at 8:48pm
Yes. Also, would 4x work?

Okay I understand thank you both.
