Question

explian how to do 

the cubed root of -125x^4y^6

walk me through it and explain how to get the answer. 

Answer 1

Rewrite the expression using only exponents.

 

(-5³ * x⁴ * y⁶)^1/3

 

 

Applying the rules of exponents,

 

(-5³)^1/3 * (x⁴)^1/3 * (y⁶)^1/3 =

 

-5^(3/3) * x^(3/3) * x^(1/3) * y^(6/3) =

 

-5xy² * ( ³√x)
