Square Root of 426 Squared (√426^2)

Square Root of 426 Squared

Here we will discuss and calculate the square root of 426 squared. The problem in mathematical terms that we want to solve is displayed below:

√426²

We are doing two math operations: The radical sign √ means that you are taking the square root of 426 and the ² means to square 426. 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 426. Nevertheless, read on because we will show you different ways of calculating the square root of 426 squared to prove that the answer is 426.

We start by first taking the square root of 426 and then square that result to get our answer like this:

√426 = 20.6398

20.6398² = 426

Now, we will do the operations in opposite order where we first square 426 and then calculate the square root of the result:

426² = 181476

√181476 = 426

You may also find this math rule interesting when dealing with a problem like the square root of 426 squared:

√x² = √x · √x

It also proves that the square root of 426 squared equals 426.

√426² = √426 · √426

√426 · √426 = 20.6398 · 20.6398

20.6398 · 20.6398 = 426
