Evaluate The Left-hand Side To Find The Value Of $a$ In The Equation In Simplest Form.$\frac{x^{\frac{5}{3}}}{x^{\frac{3}{2}}}=x^a$

Introduction

In mathematics, exponents are a fundamental concept used to represent repeated multiplication of a number. When dealing with equations involving exponents, it's essential to simplify them to their simplest form to solve for unknown variables. In this article, we will evaluate the left-hand side of the equation $\frac{x^{\frac{5}{3}}}{x^{\frac{3}{2}}}=x^a$ to find the value of $a$ in the simplest form.

Understanding Exponents

Exponents are a shorthand way of representing repeated multiplication of a number. For example, $x^2$ means $x$ multiplied by itself, which is equal to $x \times x$. Similarly, $x^3$ means $x$ multiplied by itself three times, which is equal to $x \times x \times x$. Exponents can also be negative, which means taking the reciprocal of the base number. For instance, $x^{-2}$ means $\frac{1}{x^2}$.

Simplifying the Left-Hand Side

To simplify the left-hand side of the equation, we need to apply the quotient rule of exponents, which states that when dividing two powers with the same base, we subtract the exponents. In this case, the base is $x$, and the exponents are $\frac{5}{3}$ and $\frac{3}{2}$. Applying the quotient rule, we get:

$$\frac{x^{\frac{5}{3}}}{x^{\frac{3}{2}}} = x^{\frac{5}{3} - \frac{3}{2}}$$

Simplifying the Exponent

To simplify the exponent, we need to find a common denominator, which is 6 in this case. We can rewrite the exponents as:

$$\frac{5}{3} = \frac{10}{6}$$

$$\frac{3}{2} = \frac{9}{6}$$

Now, we can subtract the exponents:

$$\frac{10}{6} - \frac{9}{6} = \frac{1}{6}$$

Therefore, the simplified form of the left-hand side is:

$$x^{\frac{1}{6}}$$

Finding the Value of $a$

Now that we have simplified the left-hand side, we can equate it to the right-hand side of the equation:

$$x^{\frac{1}{6}} = x^a$$

Since the bases are the same, we can equate the exponents:

$$\frac{1}{6} = a$$

Therefore, the value of $a$ is $\frac{1}{6}$.

Conclusion

In this article, we evaluated the left-hand side of the equation $\frac{x^{\frac{5}{3}}}{x^{\frac{3}{2}}}=x^a$ to find the value of $a$ in the simplest form. We applied the quotient rule of exponents to simplify the left-hand side and then equated it to the right-hand side to find the value of $a$. The final answer is $\frac{1}{6}$.

Introduction

In our previous article, we discussed how to simplify exponents in equations. In this article, we will answer some frequently asked questions about simplifying exponents to help you better understand the concept.

Q: What is the quotient rule of exponents?

A: The quotient rule of exponents states that when dividing two powers with the same base, we subtract the exponents. For example, $\frac{x^m}{x^n} = x^{m-n}$.

Q: How do I simplify an exponent with a negative base?

A: To simplify an exponent with a negative base, we need to take the reciprocal of the base and change the sign of the exponent. For example, $(-x)^3 = -x^3$.

Q: Can I simplify an exponent with a fractional base?

A: Yes, you can simplify an exponent with a fractional base by finding a common denominator and simplifying the fraction. For example, $\left(\frac{x}{y}\right)^{\frac{1}{2}} = \frac{x^{\frac{1}{2}}}{y^{\frac{1}{2}}}$.

Q: How do I simplify an exponent with a variable base?

A: To simplify an exponent with a variable base, we need to apply the power rule of exponents, which states that $(x^m)^n = x^{mn}$. For example, $(x^2)^3 = x^6$.

Q: Can I simplify an exponent with a negative exponent?

A: Yes, you can simplify an exponent with a negative exponent by taking the reciprocal of the base and changing the sign of the exponent. For example, $x^{-3} = \frac{1}{x^3}$.

Q: How do I simplify an exponent with a zero exponent?

A: To simplify an exponent with a zero exponent, we need to apply the rule that any number raised to the power of zero is equal to 1. For example, $x^0 = 1$.

Q: Can I simplify an exponent with a variable exponent?

A: Yes, you can simplify an exponent with a variable exponent by applying the power rule of exponents. For example, $x^{2y} = (x^2)^y = x^{2y}$.

Q: How do I simplify an exponent with a complex number?

A: To simplify an exponent with a complex number, we need to apply the rules of exponents and the properties of complex numbers. For example, $(a+bi)^n = (a^2+b^2)^{\frac{n}{2}}[cos(n\theta)+isin(n\theta)]$, where $a$, $b$, and $\theta$ are real numbers.
