Question

rewrite in simplified radical form

Answer 1

\[\sqrt{8x^6}\]?

Answer 2

or
\[\sqrt{18x^6}\]

Answer 3

the second one

Answer 4

\[18=9\times 2\] and so
\[\sqrt{18}=\sqrt{9\times 2}=\sqrt{9}\times \sqrt{2}=3\sqrt{2}\]
also
\[\sqrt{x^6}=\sqrt{(x^3)^2}=x^3\]
your answer is therefore
\[\sqrt{18x^6}=3x^3\sqrt{2}\]

Answer 5

Example:
\[\Large{\sqrt{4x^{3}} = \sqrt{(2x)^{2}x} = \sqrt{(2x)^{2}} \sqrt{x} = 2x \sqrt{x}}\]

Answer 6

@satellite73 LOL, had that ready didja? :)
