Question 44

If the square root of a number is between 6 and 7, then the cube root of the number wil be between

Solution

Since the square root of a number is between 6 and 7.

So, number itself will lie between $$6^2 = 36$$ and $$7^2 = 49$$

Cube root of 36 = 3.3 (Approx)

Cube root of 49= 3.66 (Approx)

Hence, the cube root of the number will be between 3 and 4.
