Question 175675
13) Simplify {{{sqrt(45x^23)}}}
:

14) Simplify 4th root of (x^5 divided by 16y^15)
we can write this:
{{{((x^5)/(16y^15))^(1/4)}}} = {{{(x^(5/4))/(16^(1/4)y^(15/4))}}} = {{{(x^(5/4))/(2y^(15/4))}}}
:


15) Simplify (x1/4 y1/2)2(x2y3)1/2
Assume this means: {{{(x^(1/4)*y^(1/2))^2}}} * {{{(x^2*y^3 )^(1/2)}}}
{{{x^(2/4)*y^(2/2)}}} * {{{(x^(2/2)*y^(3/2) )}}} = {{{x^(1/2)*y}}} * {{{x*y^(3/2) }}} = {{{x^(3/2)*y^(5/2)}}} or {{{sqrt(x^3*y^5)}}}
