We have negative 4 squared times negative 4 cubed times negative 4 squared.
00:05
And notice how we have parentheses.
00:07
The parentheses here are needed because, well, a little side note, right, negative 4 squared is different than negative 4 squared.
00:17
This here, negative 4 squared, is the opposite of 4 squared.
00:22
The exponent only applies here to the 4, so this would actually be equal to negative 16, whereas negative 4 squared.
00:30
Right, negative 4, squared, we'll take negative 4 times negative 4, and therefore we'd have a negative times a negative to be a positive.
00:38
So this would be equal to a positive 16.
00:41
But these are different.
00:42
But here we do have negative 4 to squared times negative 4 cubed times negative 4 squared.
00:49
So we have the same base, which is negative 4 raised the different exponents, and we're multiplying...
