Answer 1

Answer:

Step 1: Form groups of three starting from the rightmost digit of 91125.

91 125.

Step 2: Take 125. The digit 5 is at its one's place. We take the one's place of the required cube root as 5.

Step 3: Take the other group, i.e., 91. Cube of 4 is 64, and cube of 5 is 125. 91 lies between 64 and 125.
