Why do we need to estimate the square root or cube root?

Estimating the square root or cube root of a number can be useful in situations where we need to quickly approximate the value of a number without using a calculator. Estimating roots can be helpful in a variety of real-life scenarios, such as estimating the size of a room, calculating an approximate answer in a math problem, or making quick calculations in everyday life.

Estimating roots can also help in understanding the relationship between different numbers and can improve mental math skills. It can be a valuable skill to have in situations where precise calculations are not necessary and can save time and effort in solving problems.
