Answer 1

Answer:

21

Step-by-step explanation:

Smallest four digit number which is a perfect cube is 10. 10³=1000

Hence,

10261-1000=9261

We want to find the cube root of 9261.

Now, we know that 20³=8000. Thus the cube root of 9261 must be greater than 20, and it must end with a one.

Try: 21. We have 21×21=441 and 441×21=9261.

Hence, the answer is cube root of 9261 that is, 21.
