Question

What is the value of -√484?

Select one:
a. 242
b. 22
c. -22
d. -242

Answer 1

It'll be -22.

Radicals cannot normally be negative. But the question is asking for the negative of a certain radical, not for a negative radical. It isn't asking, for example, for √-484. It is asking for -(√484).

So √484 is 22, and -(22) is -22.
