Question

EXPRESS IN SIMPLEST RADICAL FORM. ALL VARIABLE REPRESENT POSITIVE REAL NUMBERS

Answer 1

\[4/5 \sqrt{72XY ^{3}}\]

Answer 2

You can break this up and take the square roots seperately.
It can be expressed as \[4/5 * \sqrt{72} *\sqrt{x} *\sqrt{y ^{3}}\]
\[4/5*6*\sqrt{2}*\sqrt{x} * y \sqrt{y}\]
this can be simplified to
\[24y/5* \sqrt{2xy}\]
