Question

Find the decimal form of the sum below 1/5+1/5²+1/5³

Answer 1

Answer:

0.248

Step-by-step explanation:

0.2 +(0.2)^2 +(0.2)^3

0.2+0.04+0.008

0.248

Answer 2

The decimal form of the sum 1/5+1/5²+1/5³ will be 0.248

The given sum here is: 1/5+1/5²+1/5³

To find the sum in the decimal form we will first convert each fraction in decimal form and then find their sum.

We will find the decimal values of each of the numbers by dividing the numerator with the denominator.

1/5 = 0.2

1/5² = 1/25 = 0.04

1/5³ = 1/125 = 0.008

Now we will find the sum of these three numbers in decimal form

1/5+1/5²+1/5³ = 0.2 + 0.04 + 0.008 = 0.248

Therefore the decimal form of the given sum will be 0.248
