Simplify a radical

Teaching Transcript

🎙️

Let's simplify the square root of 63

First let's find the prime factors. 63 is 3 times 3 times 7

Now we can identify any squared factors that we can remove. We have a 3 squared, so we can remove a 3

So the square root of 63 is 3 times the square root of 7

This math skill teaches how to simplify a square root by identifying and removing squared prime factors from the radicand. This involves factorizing the number under the square root, identifying squared factors, and simplifying the expression accordingly.
