Explanation of 9**1/2 needed

Question

I came across the example showing( 9**1/2 = 3 )in the JavaScript course and while I get that the square root of 9 is 3 I have a hard time understanding what exactly the 0.5( 1/2 ) does here, can someone please explain it to me?

Answer 1

a number raised to the power of 0.5 is the same as taking the square root of that same number.

Thank you very much

Answer 3

Equel
It is because of the following math rule:
a**(1/n) = a¹ᐟⁿ = ⁿ√a
In your example:
3 = ²√9 = 9**(1/2) = 9**0.5
