Here we will discuss and calculate the square root of 777 squared. The problem in mathematical terms that we want to solve is displayed below:
√777²
We are doing two math operations: The radical sign √ means that you are taking the square root of 777 and the ² means to square 777. 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 777. Nevertheless, read on because we will show you different ways of calculating the square root of 777 squared to prove that the answer is 777.
We start by first taking the square root of 777 and then square that result to get our answer like this:
√777 = 27.8747
27.8747² = 777
Now, we will do the operations in opposite order where we first square 777 and then calculate the square root of the result:
777² = 603729
√603729 = 777
You may also find this math rule interesting when dealing with a problem like the square root of 777 squared:
√x² = √x · √x
It also proves that the square root of 777 squared equals 777.
√777² = √777 · √777
√777 · √777 = 27.8747 · 27.8747
27.8747 · 27.8747 = 777
