Question 154419
(fourth root of (48x^42y^52))
--------------
= {{{sqrt(sqrt(48x^42*y^52))}}}
Factor out all integer 4th power terms
= {{{sqrt(sqrt(16x^40*3x^2*y^52))}}}
Remove 4th power terms from the radicals
= {{{2x^10*y^13*sqrt(sqrt(3x^2))}}}
Remove x^2 term from one radical
= {{{2x^10*y^13*sqrt(x*sqrt(3))}}}
That's all that can be done.
