The concept of square roots is fundamental in mathematics, particularly in algebra and geometry. The square root of a number is a value that, when multiplied by itself, gives the original number. In this article, we will explore the square root of 98 in radical form simplified.
What is the Square Root of 98?
The square root of 98 can be calculated using a calculator or estimated using mental math tricks. However, in radical form, we can simplify it by finding perfect square factors.
Finding Perfect Square Factors
To simplify the square root of 98, we need to find perfect square factors. A perfect square is a number that can be expressed as the product of an integer with itself. For example, 16 is a perfect square because it can be expressed as 4 × 4.
The prime factorization of 98 is 2 × 7 × 7. We can see that 7 is repeated twice, which means it is a perfect square.
Simplifying the Square Root of 98
Using the perfect square factor, we can simplify the square root of 98 as follows:
√98 = √(2 × 7 × 7) = √(2) × √(7 × 7) = √2 × 7
So, the square root of 98 in radical form simplified is √2 × 7.
How to Simplify Radical Expressions
Simplifying radical expressions involves finding perfect square factors and combining them with the square root symbol. Here are the general steps:
- Find the prime factorization of the number inside the square root.
- Identify perfect square factors by looking for repeated prime factors.
- Combine the perfect square factors with the square root symbol.
- Simplify the expression by multiplying the perfect square factors.
Example: Simplifying the Square Root of 48
The prime factorization of 48 is 2 × 2 × 2 × 2 × 3. We can see that 2 is repeated four times, which means it is a perfect square.
√48 = √(2 × 2 × 2 × 2 × 3) = √(2 × 2) × √(2 × 2) × √3 = 4 × √3
So, the square root of 48 in radical form simplified is 4√3.
