An expression is shown below. For which value of x should the expression be further simplified?

Question

sqrt14x

A) 11

B) 5

C) 56

D) 39

Answer

Your presentation is unclear. The correct notation is sqrt() so everybody knows what is square rooted and what is not.

You have not explained what you are trying to ask. Simplification is just part of evaluating.

Guessing now:
A) 11 -- sqrt(14 x 11) = sqrt(154) = 12.40967365

B) 5 -- sqrt(70) = 8.366600265

C) 56 -- sqrt(280) = 16.73320053

D) 39 -- sqrt(195) = 13.96424004

No simplification involved!

Answer

C) 56

Explanation:
56 = 4 * 14

sqrt(14x) for x = 56 can be written as:

sqrt(2 * 2 * 14 * 14)
sqrt(4) * sqrt(196)
2 * 14 = 28

That's it.
