Answer:
option a
Step-by-step explanation:
y^7/8 / y^1/4
First we will accommodate the fractions
1/4 = 2/8
y^7/8 / y^2/8
Then we will subtract the exponents of the powers since they have the same base and are dividing
7/8 - 2/8 = 5/8
y^5/8
Finally we pass the 8 as radical root
8√y^5
Part A
Y (x)=2700 (1+0.04)^x
Y (x)=2700 (1.04)^x
where x is the number of years
Part B
Y (12)=2,700×(1.04)^(12)=4,322.78
Round your answer to get 4323
