How do you solve radicals with variables give me step by step! worth a few points : )

I'm going to use the example of

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:

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 = ? Yes, it does.

i hope this : )

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
