Answer:

I'm going to use the example of [tex]\sqrt[3]{8x^{3} }[/tex]

Step-by-step explanation:

Think, how will you multiply something 3 times to get 8x.

Mathematically, that is:

n * n * n = 8x

we can split the equation into two parts:

[tex]\sqrt[3]{8} * \sqrt[3]{x^{3} }[/tex]

we know 2 * 2 * 2 = 8, so, first part is equal to 2.

second part: x * x * x = x^3, so, that is equal to x.

so the answer will be 2x.

check ur work: 2x * 2x * 2x = [tex]\sqrt[3]{8x^{3} }[/tex]? Yes, it does.
