00:14	com . Again we start this problem by applying the
00:18	power rule to simplify negative two R squared . We
00:23	would first square the coefficient of negative two . So
00:27	we have negative two squared or negative two times negative
00:31	two . Which is positive . For think of our
00:36	as our to the first . And multiplying the exponents
00:41	we have R squared , multiply what we have times
00:48	negative five are square to the third , Which simplifies
00:53	as negative five cubed Or negative five times negative five
00:59	times negative five Which is -125 . And multiplying our
01:08	exponents we have Are to the 6th . To simplify
01:15	further , we apply the product rule for our powers
01:19	and multiply the coefficients together so we have four times
01:23	negative 1 25 which is negative 500 . And for
01:30	our powers we add the exponents 2-plus 6 . So
01:35	we have our to the 8th . The answer is
01:39	negative . 500 are to the 8th . It's very
01:44	important to understand that when squaring a negative , you
01:48	end up with a positive , but when cubing a
01:52	negative , you end up with a negative .
