Answer:
600
Step-by-step explanation:
Because the tens digit is less than 5, round down to 600
The error was in second step.
3√(y^3)^4 = y^4
(Cube root cancels cube and not power 4)
The answer should be:
xy^4/4
//Hope it helps.
There is no way to factor this so i would assume the answer is no solution.
1. Ten
2. Hundred
Hope this helps
