Simplify the algebraic expression.?
√(9xy²z³)
Few people seem to get these. On similar problems incorrect answers tend to prevail.

I think I see what you did there...
Is it because the answer is actually 3 |yz| √(xz)?

±(3yz)√xz
People tend to forget that a square root can be plus or minus. A square root is not a function, because a function is defined to be single valued.

First, separate out all factors that are
perfect squares: √(9y^2z^2)(xz)
By properties of radicals, this = √9y^2z^2 * √xz,
which = 3yz√xz

√(3•3•x•y•y•z•z•z)
For each pair of factors, one moves outside the radical so
3yz√(xz)
?
√(9xy²z³)
= 3yz√(xz)
