Transcript

00:01 Here, we want to know what rational expression exponent represents a square root.

00:07 So a square root, say like the square root of x, for example.

00:11 Well, a square root is really hard to work with in a lot of ways.

00:15 And so we want to rewrite that sometimes.

00:18 And so if i wanted to rewrite that, i would rewrite this to the 1 over the root power.

00:25 So this would be to the 1 over 2 power.

00:28 So that's what they're saying.

00:29 So the answer here is 1 half.

00:31 Notice the same thing is true for any root...
