SI

You are told that 1,331 is a perfect cube. Can you guess without factorisation what is its
cube root? Similarly, guess the cube roots of 4913, 12167, 32768.​

Answer 1

Answer:

Yes, we can guess.

1331 is the cube root of 11 because the cube root of 1 is 1 and the given number ends with 1

4913 can also be guessed similarly. 7 cube ends with 3. so the cube root is 17

12167 and 32768 can also be guessed in a similar way. They are the cube roots of 23 and 32.

Hope it helps you!!
