All right, so they're asking us to do e to the negative 1 half here.
00:04
This is just a simple evaluate the expression problem where we're just going to basically need to plug this into the calculator.
00:11
So the real test here is can we figure out how to plug it into the calculator correctly.
00:15
Recognize that e is its own number.
00:18
It's like pi.
00:18
Okay, pie is a symbol, but you know that pie represents a specific number.
00:23
It's not like x, y, or z where you can just pick whatever you want.
00:26
E is the same way.
00:27
E represents roughly 2 .718 and some more junk, but it is a run -on decimal.
00:33
So we need to use the calculator because you can't just be typing in yourself.
00:37
So somewhere on your calculator there should be probably an e to the x button.
00:43
It might be e and then have a box there instead of x, just showing that that's your place to input.
00:50
But it should be one of these.
00:51
You're not looking for a capital e.
00:53
You're looking for a lowercase e with an exponent button.
00:57
There...
