Square Root of 831 Squared (√831^2)

Square Root of 831 Squared

Here we will discuss and calculate the square root of 831 squared. The problem in mathematical terms that we want to solve is displayed below:

√831²

We are doing two math operations: The radical sign √ means that you are taking the square root of 831 and the ² means to square 831. It does not matter which order you do the math operations in, because the following two math rules result in the same answer:

√x² = x

(√x)² = x

Based on those two rules, you can conclude that the answer to our problem is 831. Nevertheless, read on because we will show you different ways of calculating the square root of 831 squared to prove that the answer is 831.

We start by first taking the square root of 831 and then square that result to get our answer like this:

√831 = 28.8271

28.8271² = 831

Now, we will do the operations in opposite order where we first square 831 and then calculate the square root of the result:

831² = 690561

√690561 = 831

You may also find this math rule interesting when dealing with a problem like the square root of 831 squared:

√x² = √x · √x

It also proves that the square root of 831 squared equals 831.

√831² = √831 · √831

√831 · √831 = 28.8271 · 28.8271

28.8271 · 28.8271 = 831
