Square Root of 9999 Squared (√9999^2)

Square Root of 9999 Squared

Here we will discuss and calculate the square root of 9999 squared. The problem in mathematical terms that we want to solve is displayed below:

√9999²

We are doing two math operations: The radical sign √ means that you are taking the square root of 9999 and the ² means to square 9999. 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 9999. Nevertheless, read on because we will show you different ways of calculating the square root of 9999 squared to prove that the answer is 9999.

We start by first taking the square root of 9999 and then square that result to get our answer like this:

√9999 = 99.995

99.995² = 9999

Now, we will do the operations in opposite order where we first square 9999 and then calculate the square root of the result:

9999² = 99980001

√99980001 = 9999

You may also find this math rule interesting when dealing with a problem like the square root of 9999 squared:

√x² = √x · √x

It also proves that the square root of 9999 squared equals 9999.

√9999² = √9999 · √9999

√9999 · √9999 = 99.995 · 99.995

99.995 · 99.995 = 9999
