Simplifying a radical expression like 4/Sqrt98 can seem daunting, but it can be broken down into manageable steps. Here's a simplified guide on how to simplify 4/Sqrt98 in three easy steps.
First, let's understand what Sqrt98 means. Sqrt is short for square root, which is a mathematical operation that finds the number that, when multiplied by itself, gives the original value. For instance, Sqrt16 = 4 because 4 multiplied by 4 equals 16.
Now, let's dive into simplifying 4/Sqrt98.
Step 1: Simplify the Radical
To simplify Sqrt98, we need to find the largest perfect square that divides 98. A perfect square is a number that can be expressed as the square of an integer, such as 1, 4, 9, 16, etc.
98 can be factored as 2 x 49. And 49 is a perfect square, because it's equal to 7 squared (7^2 = 49).
So, we can rewrite Sqrt98 as Sqrt(2 x 49) or Sqrt2 x Sqrt49.
Now, since Sqrt49 is equal to 7, we can simplify further:
Sqrt98 = Sqrt2 x 7
Step 2: Simplify the Fraction
Now that we have simplified the radical, we can rewrite the original expression as:
4/Sqrt98 = 4/(Sqrt2 x 7)
To simplify this fraction, we can multiply both the numerator and the denominator by the square root of 2, which will eliminate the radical in the denominator:
4/(Sqrt2 x 7) = (4 x Sqrt2)/(Sqrt2 x Sqrt2 x 7)
Simplifying further, we get:
(4 x Sqrt2)/(2 x 7) = (4 x Sqrt2)/14
Step 3: Final Simplification
We can simplify the fraction further by dividing both the numerator and the denominator by 2:
(4 x Sqrt2)/14 = (2 x Sqrt2)/7
And that's the simplified form of 4/Sqrt98.
In conclusion, simplifying a radical expression like 4/Sqrt98 requires breaking it down into manageable steps. By simplifying the radical, simplifying the fraction, and performing final simplification, we can arrive at the simplified form of 4/Sqrt98, which is (2 x Sqrt2)/7.
Additional Tips and Tricks:
- Always look for perfect squares when simplifying radicals.
- Multiply and divide fractions by the same value to eliminate radicals in the denominator.
- Simplify fractions by dividing both the numerator and the denominator by common factors.
Actionable Takeaways:
- Practice simplifying radicals with different values.
- Use online resources or calculators to check your work.
- Break down complex problems into manageable steps.
