P^3×q^2(p^4×q^n×r^3/r^-4)=p^7q^5r^7

what does n=

Step-by-step explanation:

Given:

The equation given is:

We simplify the given equation using the following law of indices:

Therefore,

Since the base on both the sides is same, therefore, their exponents must also be same. This gives,

Therefore, the value of 'n' is 3.

80

step-by-step explanation:

all of the measures need to be converted to the same measure; such as inches. if you do that it is easy to determine which is the longest, 2500 mm which is approximately 97.5 inches.
