Square Root of 198 Squared (√198^2)

Square Root of 198 Squared

Here we will discuss and calculate the square root of 198 squared. The problem in mathematical terms that we want to solve is displayed below:

√198²

We are doing two math operations: The radical sign √ means that you are taking the square root of 198 and the ² means to square 198. 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 198. Nevertheless, read on because we will show you different ways of calculating the square root of 198 squared to prove that the answer is 198.

We start by first taking the square root of 198 and then square that result to get our answer like this:

√198 = 14.0712

14.0712² = 198

Now, we will do the operations in opposite order where we first square 198 and then calculate the square root of the result:

198² = 39204

√39204 = 198

You may also find this math rule interesting when dealing with a problem like the square root of 198 squared:

√x² = √x · √x

It also proves that the square root of 198 squared equals 198.

√198² = √198 · √198

√198 · √198 = 14.0712 · 14.0712

14.0712 · 14.0712 = 198
