Square Root of 5 Squared
Here we will discuss and calculate the square root of 5 squared. The problem in mathematical terms that we want to solve is displayed below:
We are doing two math operations: The radical sign √ means that you are taking the square root of 5 and the ² means to square 5. 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 5. Nevertheless, read on because we will show you different ways of calculating the square root of 5 squared to prove that the answer is 5.
We start by first taking the square root of 5 and then square that result to get our answer like this:
√5 = 2.2361
2.2361² = 5
Now, we will do the operations in opposite order where we first square 5 and then calculate the square root of the result:
5² = 25
√25 = 5
You may also find this math rule interesting when dealing with a problem like the square root of 5 squared:
√x² = √x · √x
It also proves that the square root of 5 squared equals 5.
√5² = √5 · √5
√5 · √5 = 2.2361 · 2.2361
2.2361 · 2.2361 = 5
