So we have x to the seventh over x to the 15th.
00:03
What does that equal? well, you could think of it as x to the 7 minus 15th.
00:09
They have same base, and i'm dividing.
00:13
Well, 7 minus 15 is 7, 8, 9, 10, 11, 12, 13, 14, 15, negative 8.
00:19
So i couldn't say this as well, x to the negative 8.
00:24
We want to write this with positive exponents.
00:26
Well, x to the negative 8, well, that's equal to 1...
