What is the simplified form of the following expression?

[tex]\[
\sqrt{\frac{16}{49}}
\][/tex]

A. [tex]\(\frac{4}{7}\)[/tex]
B. [tex]\(\frac{2}{7}\)[/tex]
C. [tex]\(\frac{4}{14}\)[/tex]
D. [tex]\(\frac{2}{14}\)[/tex]



Answer :

To simplify the expression
[tex]\[ \sqrt{\frac{16}{49}} , \][/tex]

we can follow these steps:

1. Recognize that the square root of a fraction is the same as the fraction of the square roots of the numerator and the denominator. This property is expressed mathematically as:
[tex]\[ \sqrt{\frac{a}{b}} = \frac{\sqrt{a}}{\sqrt{b}} \][/tex]

2. Identify the numerator and the denominator of the given fraction. Here, we have:
[tex]\[ \frac{16}{49} \][/tex]

3. Find the square root of the numerator. The numerator is 16, and the square root of 16 is:
[tex]\[ \sqrt{16} = 4 \][/tex]

4. Find the square root of the denominator. The denominator is 49, and the square root of 49 is:
[tex]\[ \sqrt{49} = 7 \][/tex]

5. Combine these results to form the simplified fraction:
[tex]\[ \frac{\sqrt{16}}{\sqrt{49}} = \frac{4}{7} \][/tex]

6. Lastly, we can conclude that the original expression simplifies to:
[tex]\[ \sqrt{\frac{16}{49}} = \frac{4}{7} \approx 0.5714285714285714 \][/tex]

By breaking down the problem into these steps, we see that the simplified form of
[tex]\[ \sqrt{\frac{16}{49}} \][/tex]
is
[tex]\[ \frac{4}{7} . \][/tex]
