To solve this problem you must apply the proccedure shown below.
1. You have to divide M²N³/P ³by MP/N². First, you need to rewrite the expressions:
M²N³/P³ ÷ MP/N²
2. Then, you have:
(M²N³)(N²)/(P³)(MP)
M²N^5/MP^4
3. When you simplify the expression, you obtain:
MN^5/P^4
The correct answer is the option B: MN^5/P^4
