What is the expression in radical form? (3x ^ 2) ^ (2/3)

1 answer

To express \((3x^2)^{(2/3)}\) in radical form, you can follow these steps:

  1. The exponent \((2/3)\) indicates that you will take the cube root (because of the denominator 3) and then square the result (because of the numerator 2).

  2. In radical form, this expression can be rewritten as: \[ \sqrt[3]{(3x^2)^2} \]

  3. Now, simplify \((3x^2)^2\): \[ (3x^2)^2 = 3^2 \cdot (x^2)^2 = 9x^4 \]

  4. Now substitute this back into the radical expression: \[ \sqrt[3]{9x^4} \]

So, the expression \((3x^2)^{(2/3)}\) in radical form is: \[ \sqrt[3]{9x^4} \]
