Question

Multiply and simplify by factoring. Assume that all expressions under radicals represent non negative numbers
^3√y^4 * ^3√81y^5

Answer 1

i assume those ^3 mean third root, so you have y^4/3* (81*y^5)^(1/3)

Answer 2

this would become y^(6/3)*81^(1/3)

Answer 3

which is y^2*81^(1/3) (doesn't simplify any more)

Answer 4

\[y^2*\sqrt[3]{81}\]
