Mastering these rules is a fundamental skill in algebra, opening doors to more complex problem-solving. So, let's get started and make simplifying expressions a piece of cake. This detailed guide ensures you grasp the core concepts, providing you with the tools to confidently tackle similar problems in the future. We will carefully explain each step, ensuring clarity and reinforcing your understanding of the underlying principles. Ready? Let's go!

Step-by-Step Simplification

Alright guys, let's break down this expression step by step. The expression is $\frac{x^{{\frac{1}{3}}}{x}{-\frac{3}{2}} x^{\frac{1}{2}}}$. Our main goal here is to use the rules of exponents to rewrite this in a simpler form. Remember, the key is to apply the rules correctly and keep track of each operation. We'll start with the denominator.

Combining Terms in the Denominator

First, we need to simplify the denominator, which is $x^{-\frac{3}{2}} x^{\frac{1}{2}}$. Here, we are multiplying two terms with the same base, which is 'x'. When you multiply terms with the same base, you add the exponents. This is a crucial rule in exponents. So, we'll add the exponents -3/2 and 1/2.

Adding the exponents:

$$-{\frac{3}{2}} + {\frac{1}{2}} = -{\frac{2}{2}} = -1$$

So, the denominator simplifies to $x^-1}$. Now, our expression looks like this $\frac{x^{\frac{1{3}}}{x^{-1}}$. See? We're making progress. Understanding how to combine terms in the denominator is a building block for more complex problems. Remember that the rule applies only when the bases are the same. This is a common pitfall, so pay close attention to the base of each term. Keep practicing, and you will become a pro in no time.

Dealing with Division

Now, we have $\frac{x^{{\frac{1}{3}}}{x}{-1}}$. When you divide terms with the same base, you subtract the exponents. In this case, we're dividing $x^{\frac{1}{3}}$ by $x^{-1}$. Therefore, we will subtract the exponent of the denominator (-1) from the exponent of the numerator (1/3). Another key rule to remember. Let's do it step by step to avoid mistakes.

Subtracting the exponents:

$${\frac{1}{3}} - (-1) = {\frac{1}{3}} + 1 = {\frac{1}{3}} + {\frac{3}{3}} = {\frac{4}{3}}$$

So, the expression simplifies to $x^{\frac{4}{3}}$. We are almost there! Remember, subtracting a negative number is the same as adding a positive number. That's a fundamental rule of arithmetic that often trips people up. Always double-check your signs.

Final Answer with Positive Exponents

Great job, everyone! After simplifying, the expression $\frac{x^{{\frac{1}{3}}}{x}{-\frac{3}{2}} x^{\frac{1}{2}}}$ simplifies to $x^{\frac{4}{3}}$. This is our final answer, and it uses only positive exponents, which is exactly what the question asked for. We have successfully used the rules of exponents to simplify the given expression. Pretty neat, huh? Let's recap what we did.

Summary of Steps

1. Combined Terms in the Denominator: We multiplied the terms in the denominator, adding their exponents: $x^{-\frac{3}{2}} x^{\frac{1}{2}} = x^{-1}$. Remember, adding the exponents is the key here!
2. Divided the Terms: We divided the numerator by the simplified denominator, subtracting the exponents: $\frac{x^{{\frac{1}{3}}}{x}{-1}} = x^{\frac{4}{3}}$.
3. Final Result: The simplified expression is $x^{\frac{4}{3}}$. This expression only has positive exponents. Always make sure to check if you have followed the instructions of the question.

We started with a complex-looking expression and, by applying the rules of exponents step-by-step, we were able to simplify it significantly. This process not only solves the problem but also reinforces the underlying principles of exponent manipulation. Keep practicing these rules, and you'll be able to tackle even more complex expressions with ease. Remember to always double-check your calculations, especially the signs of the exponents. Now, you are equipped with the knowledge to simplify expressions using the rules of exponents. Congratulations, and keep practicing!
