Question

I need help please!!!!

Answer 1

Let's work this problem from inside the parentheses.

(
`( w^(15) )/( w^(5) )` simplifies to
`w^(10)`
Now we have

`(w^(10))^(4)` which simplifies to
`w^(40)`

Final Answer:
`w^(40)`

Answer 2

`\left((w^(15))/(w^5)\right)^4=\left(w^(15-5)\right)^4=\left(w^(10)\right)^4=w^(10\cdot4)=w^(40)\\\\\text{Answer:}\ \boxed{w^(40)}\\\\\text{Used:}\\\\(a^n)/(a^m)=a^(n-m)\\\\\left(a^n\right)^m=a^(n\cdot m)`
