Answer for screen readers
The simplified expression for $x^{\frac{3}{2}}$ is $x \sqrt{x}$.
Steps to Solve
- Identify the Expression with Rational Exponents
First, take a close look at the expression you want to simplify. Identify any parts of the expression that contain rational exponents. For example, if you have $x^{\frac{3}{2}}$, the rational exponent is $\frac{3}{2}$, which means you can rewrite it in radical form.
- Convert Rational Exponents to Radical Form
The next step is to convert the rational exponents into radical form. The expression $x^{\frac{3}{2}}$ can be rewritten as:
$$ x^{\frac{3}{2}} = \sqrt{x^3} $$
This means you're taking the square root of $x^3$.
- Simplify the Radical If Possible
Now, simplify the radical if possible. For example, $\sqrt{x^3}$ can be simplified further.
Using the property of square roots:
$$ \sqrt{x^3} = \sqrt{x^2 \cdot x} = \sqrt{x^2} \cdot \sqrt{x} = x \sqrt{x} $$
So, by simplifying, you find that:
$$ x^{\frac{3}{2}} = x \sqrt{x} $$
- Combine the Steps
Put everything together to find the final simplified expression.
Now you have the expression in a simpler form.
The simplified expression for $x^{\frac{3}{2}}$ is $x \sqrt{x}$.
More Information
Rational exponents are a crucial part of algebra that can often make expressions more manageable. They provide a link between polynomial expressions and roots, allowing for easier manipulation and simplification.
Tips
- Misinterpreting the rational exponent by forgetting to apply both the numerator and denominator correctly when converting to radical form.
- Not simplifying the radical completely, leading to an incomplete answer.
