Answer

\[ \frac{1}{\left(x^{2}+2\right)^{-\frac{5}{3}}} = \sqrt[3]{\left(x^{2}+2\right)^{5}} \]

Solution

Simplify the expression by following steps: - step0: Solution: \(\left(x^{2}+2\right)^{\frac{5}{3}}\) - step1: Simplify: \(x^{2}\sqrt[3]{\left(x^{2}+2\right)^{2}}+2\sqrt[3]{\left(x^{2}+2\right)^{2}}\) Calculate or simplify the expression \( 1/(x^2 + 2)^(-5/3) \). Simplify the expression by following steps: - step0: Solution: \(\frac{1}{\left(x^{2}+2\right)^{\frac{-5}{3}}}\) - step1: Rewrite the fraction: \(\frac{1}{\left(x^{2}+2\right)^{-\frac{5}{3}}}\) - step2: Express with a positive exponent: \(\frac{1}{\frac{1}{\left(x^{2}+2\right)^{\frac{5}{3}}}}\) - step3: Multiply by the reciprocal: \(1\times \left(x^{2}+2\right)^{\frac{5}{3}}\) - step4: Multiply: \(\left(x^{2}+2\right)^{\frac{5}{3}}\) - step5: Simplify: \(x^{2}\sqrt[3]{\left(x^{2}+2\right)^{2}}+2\sqrt[3]{\left(x^{2}+2\right)^{2}}\) Let's break down the expression \( \frac{1}{\left(x^{2}+2\right)^{-\frac{5}{3}}} \) step by step. 1. **Understanding the Expression**: The expression can be rewritten using the property of exponents: \[ \frac{1}{a^{-b}} = a^{b} \] Therefore, we have: \[ \frac{1}{\left(x^{2}+2\right)^{-\frac{5}{3}}} = \left(x^{2}+2\right)^{\frac{5}{3}} \] 2. **Final Form**: The expression \( \left(x^{2}+2\right)^{\frac{5}{3}} \) can also be expressed in radical form: \[ \left(x^{2}+2\right)^{\frac{5}{3}} = \sqrt[3]{\left(x^{2}+2\right)^{5}} \] Thus, we conclude that: \[ \frac{1}{\left(x^{2}+2\right)^{-\frac{5}{3}}} = \sqrt[3]{\left(x^{2}+2\right)^{5}} \] Both forms are equivalent, and the simplification confirms that the expression is indeed correct.

Bonus Knowledge

The expression \( \frac{1}{\left(x^{2}+2\right)^{-\frac{5}{3}}} \) can be simplified by understanding the properties of exponents. When you have a negative exponent, it indicates that the base should be moved to the denominator. Thus, the negative sign in the exponent means you flip the expression, resulting in \( \left(x^{2}+2\right)^{\frac{5}{3}} \) in the denominator, which can also be represented as \( \frac{1}{\sqrt[3]{\left(x^{2}+2\right)^{5}}} \). This transformation is handy in both algebra and calculus, particularly when dealing with derivatives or integrals. You might encounter such forms when working through simplifications or when applying the chain rule, as it's easier to differentiate powers than fractional powers. Just remember that converting back and forth between these forms helps maintain clarity, especially in more complex problems.
