Question

$\sqrt{81}=$

00:03 Let's solve this problem together!

00:06 The square root of a number X squared cancels out the square. It's like a math magic trick!

00:17 Now, let's look at 81. We can break it down into 9 times 9, or 9 squared.

00:24 We'll apply this trick in our exercise to make solving easier.

00:28 And there you have it, the solution to our question. Great job!

To solve this problem, follow these steps:

Step 1: Understand that the square root of a number $n$ is a value that, when multiplied by itself, equals $n$ .
Step 2: Identify the number whose square is 81. Since $9 \times 9 = 81$ , the square root of 81 is 9.

Therefore, the square root of 81 is $9$ .
