​

Answer 1

Answer:

Answer

On pairing, we get,

571

787

.

Unit's digit of the given number is 7.

Least perfect cube with unit digit 7 is 27

and 27=3

3

⟹

3

27

=3.

So, unit's digit of cube root of 571787 is 3.

Now, striking out the last three digits of the given number, the number left is 571.

The largest number whose cube is less than 571 is 8....(Since, 8

3

=512 and 9

3

=729).

So, ten's digit of the cube root is 8.

Therefore, the cube root of 571787 is 83.
