Answer:

n = 2

Explanation:

As per statement of the question we will form the equation first.


((3)/(5))n-(4)/(5)=((1)/(5))n

Now we will solve the given equation to get the solution of n.


((3)/(5))n=(4)/(5)+((1)/(5))n


((3)/(5))n-((1)/(5))n=(4)/(5)


((3-1)/(5))n=(4)/(5)


((2)/(5))n= (4)/(5)

Now we cross multiply the fractions

(2×5)×n = 4×5

10.n = 20


n=(10)/(5)=2

Therefore answer is n = 2

The answer to the question should be n = 2.

This is because we can start by setting up the equation as this:

3/5n - 4/5 = 1/5n.

Next we would subtract 3/5n from both sides.

-4/5 = -2/5n.

Then we would multiply both sides by 5/-2.

2 = n.
