For this case we have the following expression:

$- \sqrt {36}$

We know that the number 36 can be rewritten as:

$36 = 6 * 6\\36 = 6 ^ 2$

We can rewrite the expression as follows:

$- \sqrt {36} = - \sqrt {6 ^ 2}$

Then, taking the square root we have:

$-\sqrt {36} = - 6$

Answer:

negative square root of 36 is:

B. -6
