Write with fractional exponents.

Hi there!

»»————-　★　————-««

I believe your answer is:

$y^\frac{2}{3}$

»»————-　★　————-««

Here’s why:

We are supposed to rewrite a radical expression as an expression with fraction exponents.

⸻⸻⸻⸻

The rule for a fraction exponent is:

$a^{\frac{x}{y}}=\sqrt[y]{a^x}\\\\\\\huge\boxed{\frac{\text{Power}}{\text{Root}}}$

⸻⸻⸻⸻

We are given the expression of $\sqrt[3]{y^2}$ .

⸻⸻⸻⸻

$\boxed{\text{Rewriting the expression:}}\\\\\sqrt[3]{y^2}\\\\\text{The '3' is the root and the '2' is the power.}\\\\\rightarrow \sqrt[3]{y^2} \\\\\rightarrow {y^{\frac{2}{3}}$

⸻⸻⸻⸻

$\text{The answer should be: } \boxed{y^\frac{2}{3} }$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Answer:

Option 4

Step-by-step explanation:

Coordinances for a three-dimensional coordinate system are (x, y, z).

The letter labeling each axis is always on the positive side.

The fourth option is correct because you move 3 units away from the 'x', 1 unit away from the 'y', then 2 units toward the 'z'.
