Understanding the Problem

The given problem involves finding the square root of a fraction, which is $\frac{900}{196}$ . To simplify this expression, we need to find the prime factorization of both the numerator and the denominator. The numerator, 900, can be factored as $2^2 \times 3^2 \times 5^2$ , while the denominator, 196, can be factored as $2^2 \times 7^2$ .

Simplifying the Fraction

To simplify the fraction, we can cancel out common factors in the numerator and the denominator. In this case, both the numerator and the denominator have a factor of $2^2$ . We can cancel out these common factors to get:

\frac{900}{196} = \frac{2^2 \times 3^2 \times 5^2}{2^2 \times 7^2} = \frac{3^2 \times 5^2}{7^2}

Finding the Square Root

Now that we have simplified the fraction, we can find the square root of the numerator and the denominator separately. The square root of $3^2 \times 5^2$ is $3 \times 5 = 15$ , while the square root of $7^2$ is 7.

Writing the Answer

Since we are asked to write the answer as a proper fraction, improper fraction, or whole number, we can write the square root of the fraction as:

\pm \sqrt{\frac{900}{196}} = \pm \frac{15}{7}

Conclusion

In conclusion, the square root of $\frac{900}{196}$ is $\pm \frac{15}{7}$ . This is a proper fraction, which is a fraction where the numerator is less than the denominator.

Final Answer

The final answer is $\boxed{\pm \frac{15}{7}}$ .

Understanding the Sign of the Answer

The given problem involves finding the square root of a fraction, which is $\frac{900}{196}$ . Since the square root of a number can be positive or negative, we need to consider both possibilities. The square root of a positive number is always positive, while the square root of a negative number is always negative.
