What is the square root to the power of 4?
We will use the concepts of exponents to solve the problem. Exponents are very important for calculations and are used in many subjects like physics.
Answer: The square root to the power 4 of a number is the square root of a number.
Let's understand the solution.
When we calculate the fourth root of a number given, we write it as (number)1/4.
It can also be written as √√(number), that is, square root of the square root of a number!
Let's take an example here.
Let us calculate the 4th root of 81.
We know that the square root of 81 is 9, that is, √81 = 9
Now, we calculate the square root of 9 which is 3, that is, √9 = 3.
Hence, the fourth root of 81 is 3, that is, 811/4 = 3.
