Introduction

Simplifying algebraic expressions is a crucial skill in mathematics, and it requires a deep understanding of various mathematical concepts, including algebraic manipulation, factoring, and the properties of square roots. In this article, we will focus on simplifying the given expression, which involves the subtraction of two square roots. We will use various mathematical techniques to simplify the expression and arrive at a final answer.

Understanding the Expression

The given expression is $\sqrt{\frac{44}{m^2}} - \sqrt{\frac{81m}{m^2}}$. To simplify this expression, we need to understand the properties of square roots and how they can be manipulated. The square root of a number is a value that, when multiplied by itself, gives the original number. In this case, we have two square roots, each with a different expression under the radical sign.

Simplifying the First Square Root

Let's start by simplifying the first square root, $\sqrt{\frac{44}{m^2}}$. We can simplify this expression by factoring the numerator and denominator. The numerator, 44, can be factored as $4 \times 11$, and the denominator, $m^2$, can be left as is. Therefore, we can rewrite the first square root as $\sqrt{\frac{4 \times 11}{m^2}}$.

Simplifying the Second Square Root

Now, let's simplify the second square root, $\sqrt{\frac{81m}{m^2}}$. We can simplify this expression by factoring the numerator and denominator. The numerator, 81, can be factored as $9 \times 9$, and the denominator, $m^2$, can be left as is. Therefore, we can rewrite the second square root as $\sqrt{\frac{9 \times 9m}{m^2}}$.

Combining the Two Square Roots

Now that we have simplified both square roots, we can combine them to get the final expression. We can rewrite the original expression as $\sqrt{\frac{4 \times 11}{m^2}} - \sqrt{\frac{9 \times 9m}{m^2}}$. To combine these two square roots, we need to find a common denominator. In this case, the common denominator is $m^2$.

Simplifying the Expression

Now that we have a common denominator, we can simplify the expression by combining the two square roots. We can rewrite the expression as $\frac{\sqrt{4 \times 11}}{\sqrt{m^2}} - \frac{\sqrt{9 \times 9m}}{\sqrt{m^2}}$. We can simplify this expression by canceling out the common factors in the numerator and denominator.

Canceling Out Common Factors

We can cancel out the common factors in the numerator and denominator by dividing both the numerator and denominator by $\sqrt{m^2}$. This gives us $\frac{\sqrt{4 \times 11}}{\sqrt{m^2}} - \frac{\sqrt{9 \times 9m}}{\sqrt{m^2}} = \frac{\sqrt{4 \times 11}}{m} - \frac{\sqrt{9 \times 9m}}{m}$.

Simplifying the Expression Further

We can simplify the expression further by simplifying the square roots in the numerator. We can rewrite the first square root as $\frac{2\sqrt{11}}{m}$ and the second square root as $\frac{9\sqrt{m}}{m}$.

Final Answer

Now that we have simplified the expression, we can rewrite it as $\frac{2\sqrt{11}}{m} - \frac{9\sqrt{m}}{m}$. This is the final answer to the given expression.
