Question 291195
That's an expression, not an equation.  Equations have an equal sign
and we end up knowing what number the letter equals to.  An expression
has no equal sign and we never know what number the letter equals to.

{{{root(4,36)sqrt(5)}}}

Since the indices of the radicals are not the same we
cannot multiply under the radicals, so we must get
the radicals to having the same index:

Write {{{36}}} as {{{6^2}}} 

{{{root(4,6^2)*sqrt(5)}}}

Write {{{root(4,6^2)}}} as {{{drawing(50,50,-1,38,-2,2,locate(0,1, 6^(2/4)) )}}}

Reduce the fraction exponent {{{2/4}}} to {{{1/2}}}

Write {{{drawing(50,50,-1,38,-2,2,locate(0,1, 6^(1/2)) )}}} as {{{sqrt(6)}}}

{{{sqrt(6)sqrt(5)}}}

Now we can multiply underneath the radicals.

{{{sqrt(6*5)}}}

{{{sqrt(30)}}}
