# What does 9 to the power of 1/2 mean?

## What does 9 to the power of 1/2 mean?

A Universal Rule Raising 9 to the 2nd power gives you 81. Now you have to get the 1st root of 81. But the 1st root of any number is the number itself, so the answer remains 81. Now look at the expression 9^1/2. So all you have to do is get the square root of 9, which is 3.

## What does the power of 1/2 mean?

Fractional exponents Taking a number to the power of 12 undoes taking a number to the power of 2 (or squaring it). In other words, taking a number to the power of 12 is the same thing as taking a square root: x1/2u221ax

## How do you do a 1/2 exponent?

Hence x to the power of 1/2 can be written as x(1/2) which is a fractional exponent. Where the number x is called the base, whereas (1/2) is the power or exponent of the expression. Any exponent of (1/2) is actually the square root of that number.

## How do you solve a fraction to a power?

How To Solve Fractional Exponents?

• Rule 1: a1/m xd7 a1/n a. (1/m + 1/n)
• Rule 2: a1/m xf7 a1/n a. (1/m – 1/n)
