If 1.5 times 10 to the fourth all to the x power equals 1,

00:09

then x must be which of the following?

00:11

And here are the potential answers...

00:15

So... even though we have a ton of parentheses and numbers here,

00:18

this is really a pretty simple question.

00:21

Ignore the numbers inside the parentheses for now.

00:27

00:29

When do we ever deal with exponents and have the result be... 1?

00:34

The answer?

00:35

ANY number to the ZERO power gives a result of 1.

00:39

Really...any number. Even 1 billion to the zero power gives a result of 1.

00:44

So x must be equal to 0.

00:47

Which means that our answer is C.
