Understanding Exponents and Radicals

Exponents and radicals are fundamental concepts in mathematics that help us simplify complex expressions and solve equations. In this article, we will explore the concept of exponents and radicals, and how to apply them to simplify the given expression (x2y3)3x2y3\frac{\left(x^2 y^3\right)^3}{\sqrt[3]{x^2 y}}.

The Power of Exponents

Exponents are a shorthand way of writing repeated multiplication. For example, x2x^2 means x×xx \times x, and x3x^3 means x×x×xx \times x \times x. Exponents can be added, subtracted, multiplied, and divided, just like regular numbers.

Radicals and Roots

Radicals are a way of expressing the square root or other roots of a number. For example, x\sqrt{x} means the square root of xx, and x3\sqrt[3]{x} means the cube root of xx. Radicals can be simplified by using the properties of exponents.

Simplifying the Expression

To simplify the expression (x2y3)3x2y3\frac{\left(x^2 y^3\right)^3}{\sqrt[3]{x^2 y}}, we need to apply the properties of exponents and radicals.

Step 1: Simplify the Numerator

The numerator is (x2y3)3\left(x^2 y^3\right)^3. Using the property of exponents that (am)n=am×n(a^m)^n = a^{m \times n}, we can simplify the numerator as follows:

(x2y3)3=x2×3y3×3=x6y9\left(x^2 y^3\right)^3 = x^{2 \times 3} y^{3 \times 3} = x^6 y^9

Step 2: Simplify the Denominator

The denominator is x2y3\sqrt[3]{x^2 y}. Using the property of radicals that an=a1n\sqrt[n]{a} = a^{\frac{1}{n}}, we can simplify the denominator as follows:

x2y3=x23y13\sqrt[3]{x^2 y} = x^{\frac{2}{3}} y^{\frac{1}{3}}

Step 3: Simplify the Expression

Now that we have simplified the numerator and denominator, we can simplify the expression as follows:

(x2y3)3x2y3=x6y9x23y13\frac{\left(x^2 y^3\right)^3}{\sqrt[3]{x^2 y}} = \frac{x^6 y^9}{x^{\frac{2}{3}} y^{\frac{1}{3}}}

Using the property of exponents that aman=amn\frac{a^m}{a^n} = a^{m - n}, we can simplify the expression further as follows:

x6y9x23y13=x623y913=x163y263\frac{x^6 y^9}{x^{\frac{2}{3}} y^{\frac{1}{3}}} = x^{6 - \frac{2}{3}} y^{9 - \frac{1}{3}} = x^{\frac{16}{3}} y^{\frac{26}{3}}

Step 4: Simplify the Expression Further

We can simplify the expression further by combining the exponents of xx and yy:

x163y263=(x163y263)x^{\frac{16}{3}} y^{\frac{26}{3}} = \left(x^{\frac{16}{3}} y^{\frac{26}{3}}\right)

Step 5: Write the Expression in Exponential Form

The expression (x163y263)\left(x^{\frac{16}{3}} y^{\frac{26}{3}}\right) is already in exponential form.

Conclusion

In this article, we have simplified the expression (x2y3)3x2y3\frac{\left(x^2 y^3\right)^3}{\sqrt[3]{x^2 y}} using the properties of exponents and radicals. We have shown that the expression can be simplified to (x163y263)\left(x^{\frac{16}{3}} y^{\frac{26}{3}}\right), which is already in exponential form.

Frequently Asked Questions

In this article, we will answer some frequently asked questions about exponents and radicals.

Q: What is the difference between an exponent and a radical?

A: An exponent is a shorthand way of writing repeated multiplication, while a radical is a way of expressing the square root or other roots of a number.

Q: How do I simplify an expression with exponents and radicals?

A: To simplify an expression with exponents and radicals, you need to apply the properties of exponents and radicals. This includes using the rules for multiplying and dividing exponents, as well as simplifying radicals.

Q: What is the rule for multiplying exponents?

A: The rule for multiplying exponents is that when you multiply two numbers with the same base, you add their exponents. For example, x2×x3=x2+3=x5x^2 \times x^3 = x^{2+3} = x^5.

Q: What is the rule for dividing exponents?

A: The rule for dividing exponents is that when you divide two numbers with the same base, you subtract their exponents. For example, x5÷x3=x53=x2x^5 \div x^3 = x^{5-3} = x^2.

Q: How do I simplify a radical?

A: To simplify a radical, you need to find the largest perfect square that divides the number inside the radical. You can then take the square root of this perfect square and simplify the radical.
