Question

Find the value of √1.21-√0.01

Answer 1

Answer:

1

Step-by-step explanation:

Root 1.21 can be written as root 121/100 which would be 11/10 = 1.1

Root of 0.01 can be written as root 1/100 = 1/10 = 0.1

Subtracting 0.1 from 1.1 gives the answer 1.

Answer 2

1.21 = 121/100 = (11/10)²

0.01  = 1/100 = (1/10)²

Therefore, the square roots are 11/10 and 1/10 respectively.

And hence the answer is 11/10 - 1/10 = 1.
