A nice challenge!
The root of a number can be expressed as a fraction by finding the reciprocal of the power and then simplifying.
In this case, we want to find the root of 125, which is denoted as √125. To convert it to a fraction, we can follow these steps:
1. Write the radical expression: √125
2. Find the perfect square that is closest to or equal to 125 (in this case, 100).
3. Express the radical as a fraction by writing it as the reciprocal of the power:
√125 = (√(100/1)) × (√((125 - 100)/1))
= (√4/1) × (√25/1)
= 2√25
4. Simplify the expression inside the square root (25 is a perfect square, so its square root is an integer):
2√25 = 2 × 5 (since √25 = 5)
= 10
So, the fraction equivalent of √125 is:
10
The Root 125 formula!
Root 125 is a popular formula for hair care, particularly for curly-haired individuals. The name "Root 125" refers to the concentration of keratin amino acids in the product (12.5%). Keratin is a protein that helps to repair and strengthen damaged hair.
Here are some benefits of using Root 125:
1. **Moisturizes and nourishes**: Root 125 helps to lock in moisture, reducing frizz and flyaways while leaving your curls soft and manageable.
2. **Repairs damage**: The keratin-based formula repairs and restores damaged hair, making it stronger and less prone to breakage.
3. **Defines curls**: Root 125 can help define curls, reduce frizz, and enhance natural texture.
4. **Soothes scalp issues**: The product is gentle enough for sensitive scalps and can help soothe itchiness, redness, and irritation.
5. **Protects from heat damage**: Using Root 125 before styling with heat tools (e.g., flat irons, curling wands) helps protect your hair from thermal damage.
Some common uses of Root 125 include:
1. As a pre-shampoo treatment to repair and moisturize dry or damaged hair.
2. As a leave-in conditioner or styling product to enhance natural texture and define curls.
3. As a spot treatment for dry, brittle ends or split ends.
Keep in mind that everyone's hair is unique, so it's essential to use Root 125 as directed and adjust the amount used based on your individual hair type and needs.
Have any specific questions about using Root 125 or curly-haired hair care in general?
To simplify the expression, we can start by finding the prime factorization of 125:
125 = 5^3
Now, we can use this fact to simplify the expression:
√125 = √(5^3)
= 5√25
We can simplify the square root inside the parentheses further by finding the prime factorization of 25:
25 = 5^2
So, we get:
5√25 = 5√(5^2)
= 5 × 5
= 25
Finding the square root of 125!
The square root of 125 is denoted by √125. To find it, you can use a calculator or do some basic math.
Here are a few methods:
**Method 1: Calculator**
Simply plug in "√125" into your calculator and press enter. The answer will be displayed as approximately 11.18.
**Method 2: Factorization**
Another way to find the square root is by factorizing 125:
125 = 5 × 25
Since √25 = 5, you can rewrite 125 as:
125 = (5)² × 5
Now, take the square root of both sides:
√125 = √((5)² × 5)
= √(5) × √5
≈ 11.18 (approximately)
**Method 3: Estimation**
If you don't have a calculator or prefer an estimate, you can use a rough estimate by finding the nearest perfect square that is less than or equal to 125. In this case, it's 121 = (11)².
Then, take the square root of both sides:
√125 ≈ √(121 + 4)
≈ √(11² + 4)
≈ 11.18 (approximately)
So, the square root of 125 is approximately 11.18.
A classic!
To find the root of a number using the division method, also known as the "long division" method, we can use the following steps:
**Finding the square root of 125 using division method:**
1. Write the number whose square root you want to find (in this case, 125).
2. Draw a line under the number and write the divisor (which is usually represented as √) above it.
3. Divide the number by a perfect square that is less than or equal to the given number. In this case, we can start with 1^2 = 1, then 2^2 = 4, then 3^2 = 9, and so on.
4. Keep dividing until you find a perfect square that is greater than or equal to the given number.
Here's how it looks:
```
_______
125 |
----
11 | (1 x 11 = 11)
--- |
100 | (2 x 50 = 100, but we're not there yet)
--- |
90 | (3 x 30 = 90, still not there...)
--- |
125 (5 x 25 = 125, finally!)
```
In this case, the square root of 125 is 11, because 11^2 = 121, which is close enough to our original number.
So, the final answer is:
√125 ≈ 11
