Formula Explained
The formula used in this calculator is based on the properties of exponents and square roots. The general form is:
Formula
√(an) = an/2
Where:
- a = base number
- n = exponent
This formula shows that the square root of a number raised to an exponent is equal to the base number raised to half of the exponent.
Important Note
This formula works when the exponent is an even number. For odd exponents, the result will be an irrational number.
Worked Examples
Let's look at some examples to understand how the calculator works.
Example 1: √(42)
