You apply the rule to put the exponent in front, and lower it by one. But since this is a nested expression, you apply it twice:
4*(5x^3-4)^3 * 3*5x^2 =
60x^2 (5x^3-4)^3
        
             
        
        
        
Answer:
The percent increase per year is 4%
Step-by-step explanation:
we have

This is a exponential function of the form

where
y represent the monthly rent at Lake View Apartments
x represent the number of years
a is the initial value (y-intercept)
b is the base
r is the rate or percent increase

The percent increase per year is the base of the exponential function decreased by 1.
so

In this problem we have
 ---> initial value
 ---> initial value

Therefore
The percent increase per year is 4%

STEP 2: We add the rounded numbers. ... 
STEP 1: Round the summands.
STEP 2: Add the rounded numbers.
STEP 3: Look at the total amount of rounding.
We have rounded the two summands down.
