Solve Square Root Addition: √16 + √4 Step by Step

Question

$\sqrt{16}+\sqrt{4}=$

00:03 Let's solve this question together.

00:07 The square root of a number, N, is equal to N itself.

00:12 We'll use this idea in our problem.

00:16 For example, 16 equals 4 to the power of 2.

00:21 And 4 equals 2 to the power of 2.

00:29 So, the square root of a number, is the number itself.

00:38 And that's how we solve the problem!

To solve this problem, we'll follow these steps:

Now, let's work through each step:

Step 1: Calculate the square root of 16.
Since 16 is a perfect square, $\sqrt{16} = 4$ .

Step 2: Calculate the square root of 4.
Since 4 is also a perfect square, $\sqrt{4} = 2$ .

Step 3: Add the results from steps 1 and 2.
Thus, $4 + 2 = 6$ .

Therefore, the solution to the problem is $6$ .
