Understanding Rational Exponents

Rational exponents are a way to express roots and powers of numbers using fractions. They are often used in algebra and other branches of mathematics to simplify complex expressions. In this article, we will explore how to convert rational exponents to radical form, using the equation $T=A^{3/2}$ as an example.

**The Equation $T=A^{3/2}$

The given equation is $T=A^{3/2}$ . This equation can be rewritten in radical form using the rule that $a^{m/n} = \sqrt[n]{a^m}$ . Applying this rule, we get:

T = A^{3/2} = \sqrt[2]{A^3} = \sqrt{A^3}

Converting to Radical Form

To convert the equation to radical form, we need to get rid of the rational exponent. We can do this by using the rule that $a^{m/n} = \sqrt[n]{a^m}$ . In this case, we have $A^{3/2}$ , which can be rewritten as $\sqrt{A^3}$ .

Simplifying the Radical Form

Now that we have the equation in radical form, we can simplify it further. We can do this by multiplying both sides of the equation by $\sqrt{A}$ to get rid of the radical:

T\sqrt{A} = A^3

Rearranging the Terms

We can rearrange the terms in the equation to get:

T\sqrt{A} - A^3 = 0

Solving for T

To solve for T, we can divide both sides of the equation by $\sqrt{A}$ :

T = \frac{A^3}{\sqrt{A}}

Simplifying the Expression

We can simplify the expression further by rationalizing the denominator:

T = \frac{A^3}{\sqrt{A}} \cdot \frac{\sqrt{A}}{\sqrt{A}} = \frac{A^3\sqrt{A}}{A} = A^2\sqrt{A}

Conclusion

In this article, we have seen how to convert the equation $T=A^{3/2}$ to radical form. We have also simplified the radical form and solved for T. The final expression is $T = A^2\sqrt{A}$ .

Discussion

Now that we have converted the equation to radical form, we can discuss the different options given in the problem.

Option A: $T^3 = A^2$

This option is not correct because it does not match the original equation.

Option B: $\frac{1}{2}T = A^3$

This option is not correct because it does not match the original equation.

Option C: $T^2 = A^3$

This option is not correct because it does not match the original equation.

Option D: $T^2 = \frac{1}{3}A$

This option is not correct because it does not match the original equation.
