Ok now I have one attempt remaining :O

Please tell me if this is correct before I submit

the cube root of 250x^19y^15z^10

answer is 5x^6y^5z^3 * cube root of 2xz

-
³√ (250x^19y^15z^10) =

³√(5³*2) x^(19/3) y^(15/3) z^(10/3)=
5³√(2) x^(19/3) y^(5) z^(10/3)=

5³√(2) ³√( x^18*x) ³√( z^9*z) y^5 =

5³√( 2) *x^6 (³√( x)) y^5 * z³* ³√( z) =
5x^6y^5z³ (³√( 2xz)
You're ok.
