When dealing with square roots of fractions, it's essential to simplify the expression before finding the final value. In this article, we'll explore the simplified form of $$\sqrt{\frac{48}{192}}$$ and provide a step-by-step guide on how to simplify square roots of fractions.

Understanding Square Roots of Fractions

A square root of a fraction can be expressed as $$\sqrt{\frac{a}{b}}$$, where $a$ and $b$ are integers. To simplify this expression, we need to find the largest perfect square that divides both $a$ and $b$ .

Simplifying the Given Expression

Let's start by simplifying the given expression $$\sqrt{\frac{48}{192}}$$. We can begin by finding the greatest common divisor (GCD) of 48 and 192.

Finding the Greatest Common Divisor (GCD)

To find the GCD of 48 and 192, we can use the Euclidean algorithm or list the factors of each number. The factors of 48 are 1, 2, 3, 4, 6, 8, 12, 16, 24, and 48. The factors of 192 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, and 192.

Identifying the Greatest Common Divisor

By comparing the factors of 48 and 192, we can see that the greatest common divisor is 48.

Simplifying the Fraction

Now that we have found the GCD, we can simplify the fraction by dividing both the numerator and the denominator by the GCD.

\sqrt{\frac{48}{192}} = \sqrt{\frac{48 \div 48}{192 \div 48}} = \sqrt{\frac{1}{4}}

Simplifying the Square Root

To simplify the square root, we can express it as a fraction with a square root in the numerator and a perfect square in the denominator.

\sqrt{\frac{1}{4}} = \frac{\sqrt{1}}{\sqrt{4}} = \frac{1}{2}

Conclusion

In this article, we have simplified the expression $$\sqrt{\frac{48}{192}}$$ by finding the greatest common divisor of 48 and 192, simplifying the fraction, and finally simplifying the square root. The simplified form of the expression is $$\frac{1}{2}$$.
