Question

Simplify the problem below....

Answer 1

\[\sqrt{28u ^{12}}\]

Answer 2

Ok, so you want to rewrite that into its factors to find out what you can take out.

\[\sqrt{4*7*u^{12}}\]
From here, you know the square root of 4 is 2, so you can take that out and rewrite it as
\[2\sqrt{7u^{12}}\]
Now \[u^{12}\] is really the same thing as \[u^{6}^{2}\], meaning you can take out the \[u^{6}\], and you are left with
\[2u^{6} \sqrt{7}}\]
