OpenStudy (phi):
square root of a number (like 36) means if you multiply it by itself you get 36
what is -6* -6 ?

-12?
OpenStudy (anonymous):
no its 36
OpenStudy (anonymous):
sorry
OpenStudy (phi):
when multiplying, 2 -'s become a + (one of those mysteries)
and 6*6 is 36
so yes,
-6* -6 is 36
that shows that -6 is a square root (of 36)
because -6 times itself = 36
OpenStudy (anonymous):
ok makes sense

so the answer is -6?
OpenStudy (phi):
yes, -6
real numbers have 2 square roots, one is positive and the other is negative
for 36, the two square roots are -6 and 6
here they want the negative square root, so that is -6
