Answer 1

Answer:

45

STEP BY STEP EXPLANATION:-

The given number 91125 can be written as 91,125

Take the last group i.e. 125

The last digit of perfect cube is 5. So, the last digit of the cube root is 5.

Therefore, the rightmost digit is 5.

Now take the next group i.e. 91.

To find the largest cube number we can subtract from 81 so that the result is ≥0

We can subtract 4 3

=64 from 81, because 81−64=17≥0(If we subtract 5

3

=125, we get 81−125=−44<0).

Thus, the next neighbour digit of the answer is 4.

Hence,

3

91125=45
