Similarly, the square root of 64 is 8, because 8 multiplied by itself gives us 64.
The Basics of Simplifying Square Roots
Now that we have a basic understanding of what a square root is, let's move on to simplifying them. To simplify a square root, we need to find the factors of the number under the radical sign (the symbol √) and then group them in pairs. We then take one number from each pair outside the radical sign and multiply them. This simplifies the square root.
For example, let's say we want to simplify the square root of 48. The factors of 48 are 2, 2, 2, 2, and 3. We can group the factors in pairs as (2,2), (2,2), and (3). We take one number from each pair outside the radical sign and multiply them, which gives us 4√3. Therefore, the simplified form of the square root of 48 is 4√3.

- 2
- 2
- 3
- 5
Then, I paired the factors in groups of two:
- 2 x 2 = 4
- 2 x 3 = 6
- 5 (cannot be paired with any other factor)
Next, I took the perfect squares out of the pairs and multiplied them:
- 4 x 6 = 24
- 5 (left alone since it doesn't have a pair)
Finally, I combined the perfect square and the remaining factor under one radical sign:
√(4 x 6 x 5) = √120
And there it is! The simplified square root of 120.
