Good evening, Riley!

Used properties:

\star~\boxed{\mathsf{a = \dfrac{ax}{x}, \ \ x\neq 0}}\\ \\ \\ \star~\boxed{\mathsf{\dfrac{\frac{a}{b}}{\frac{c}{d}} = \dfrac{ad}{bc}}}

Now, note that:

\mathsf{1 = \dfrac{x}{x},\ x\neq 0}

So:

\mathsf{\dfrac{\frac 1 x + \frac x x }{\frac 1 x} = \dfrac{\frac{x+1}{x}}{\frac 1 x}}=} \mathsf{\dfrac{x}{1}\dfrac{x+1}{x} = \boxed{x + 1}}

Write the equation using a fractional exponent<br><img src="https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%7D2" id="TexFormula1" tit
gogolik [260]

<u>Answer:</u>

The equation using a fractional exponent \sqrt[3]{x^{2}} is x^{\frac{2}{3}}

<u>Solution:</u>

Given, term is cube root of x square

In numerical terms cube root of x square can be written as ⇒ cube root of x^{2} \rightarrow \sqrt[3]{x^{2}}

We have to write the expression for above given term in the form of fractional exponent of x.

In \sqrt[3]{x^{2}} , cube root is written in fractional form

\rightarrow\left(x^{2}\right)^{\frac{1}{3}}

Now, powers are multiplied

\rightarrow x^{2 \times \frac{1}{3}}

\rightarrow x^{\frac{2}{3}}

Finally x is in power of a fraction, so we got the required answer
