Find the cube roots for each number:
3√27
3√75 - Estimate
The cube root of 27 is 3, because 3 x 3 x 3 = 27.
To estimate the cube root of 75, we can think of numbers whose cubes are close to 75. The cube of 4 is 64, and the cube of 5 is 125. So, the cube root of 75 is slightly greater than 4 but less than 5. We can estimate it to be around 4.2.
