What did we learn about in this section? well, we learn that if we take the square root of the numerator and denominator separately, then i can combine it under one square root or vice versa.
00:11
I'm taking the square of a fraction, i can take the square of a numerator and denominator.
00:15
So what i'm going to do is going to work backwards.
00:17
I'm just going to take the square root of this entire fraction, try to simplify this fraction, and then solve it.
00:25
So what's 56 divided by 2? well, 56 divided by 2 is approximately 28.
00:32
Okay, so this is square root of 28.
00:35
I can combine my x terms, write x the 5th over x the first.
00:39
This is just x to 5 minus 1, subtract the exponents, and then the y terms, subtract those exponents here...
