Answer 1

$B. \sqrt{105}$

The multiples of 105 are 3,5,and 7 so none of them can come out of the square root so it cannot be simplified.

Answer 2

Answer:

The answer is the option B

$\sqrt{105}$

Step-by-step explanation:

we have

$\sqrt{105}$

we know that

$105=3*5*7$

so

substitute

$\sqrt{105}=\sqrt{3*5*7}$ -------> it can not be simplified

therefore

the answer is

$\sqrt{105}$ ----> the expression can not be simplified
