Square Root of 781 Squared (√781^2)

Square Root of 781 Squared

Here we will discuss and calculate the square root of 781 squared. The problem in mathematical terms that we want to solve is displayed below:

√781²

We are doing two math operations: The radical sign √ means that you are taking the square root of 781 and the ² means to square 781. 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 781. Nevertheless, read on because we will show you different ways of calculating the square root of 781 squared to prove that the answer is 781.

We start by first taking the square root of 781 and then square that result to get our answer like this:

√781 = 27.9464

27.9464² = 781

Now, we will do the operations in opposite order where we first square 781 and then calculate the square root of the result:

781² = 609961

√609961 = 781

You may also find this math rule interesting when dealing with a problem like the square root of 781 squared:

√x² = √x · √x

It also proves that the square root of 781 squared equals 781.

√781² = √781 · √781

√781 · √781 = 27.9464 · 27.9464

27.9464 · 27.9464 = 781
