A usual question is come ask whether the square source of 72 is reasonable or irrational. Reasonable numbers have the right to be created as a portion and irrational number cannot.

A quick means to inspect this is to view if 72 is a perfect square. If the is, then it is a reasonable number. If it"s not a perfect square then it"s one irrational number.

We already know if 72 is a perfect square so we also can check out that √72 is an irrational number.

## Can the Square source of 72 be Simplified?

72 can be simplified just if you can make 72 inside the radical price smaller. This is a process that is dubbed simplifying the surd. In this example, the square source of 72 have the right to be simplified.

√72 = 6√2.

## How to calculate The Square root of 72 through a Calculator

If you have actually a calculator then the simplest method to calculate the square root of 72 is to use that calculator. On many calculators you can do this by inputting in 72 and also then pressing the √x key. Girlfriend should get the following result:

√72 ≈ 8.4853

## How to calculate the Square root of 72 through a Computer

On a computer you can also calculate the square root of 72 using Excel, Numbers, or Google Sheets and also the SQRT function, like so:

SQRT(72) ≈ 8.485281374239

## What is the Square source of 72 Rounded?

Sometimes you might need to ring the square source of 72 under to a certain number of decimal places. Here are the solutions to that, if needed.
