In this problem, we are asked to factor out the lowest power of the common factor, and the lowest power would be the negative three halves.
00:12
So we're factoring x to the negative three halves out of all three terms.
00:17
So with the first term, it's pretty easy to see what to do.
00:21
When you factor x to the negative three halves out of x to the negative three halves, you're just left with one.
00:26
But then it can be a little difficult to figure out how to factor x to the negative three halves out of x to the negative one half.
00:34
So how do you do that? so this is how i think of it.
00:38
X to the negative three halves times x to the what would give me x to the negative one half.
00:45
That's what we really need to figure out.
00:49
So remember with exponents, you add the powers.
00:51
So negative three halves plus what would be negative one half.
00:56
And that would have to be a positive one.
00:58
Negative three halves plus one is negative one half.
01:01
So that means when we factor out negative three have, x to the negative three halves...
