Square Root of 155 Squared (√155^2)

Square Root of 155 Squared

Here we will discuss and calculate the square root of 155 squared. The problem in mathematical terms that we want to solve is displayed below:

√155²

We are doing two math operations: The radical sign √ means that you are taking the square root of 155 and the ² means to square 155. 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 155. Nevertheless, read on because we will show you different ways of calculating the square root of 155 squared to prove that the answer is 155.

We start by first taking the square root of 155 and then square that result to get our answer like this:

√155 = 12.4499

12.4499² = 155

Now, we will do the operations in opposite order where we first square 155 and then calculate the square root of the result:

155² = 24025

√24025 = 155

You may also find this math rule interesting when dealing with a problem like the square root of 155 squared:

√x² = √x · √x

It also proves that the square root of 155 squared equals 155.

√155² = √155 · √155

√155 · √155 = 12.4499 · 12.4499

12.4499 · 12.4499 = 155
