Answer:

√(210)

Step-by-step explanation:

Let's look at the prime factors of 210.

210 = 2 * 3 * 5 * 7

√(210) = √(2 * 3 * 5 * 7) = √(210)

Since no factor appears more than once, this radical cannot be simplified.

HELPPPPP PLEASE

Answers

(12 + 3x)x

Every answer, when distributed and added, comes out to be 15x. However, (12 + 3x)x, when distributed comes out to 12x + 3x^2 (3x squared,) so this means it is not equivalent to the other answer choices.
