A positive exponent shows that the decimal point is shifted that number of places to the right.
Review of Exponents You already know that an exponent represents the number of times you have to multiply a number by itself. But what if your variable is being raised to a negative exponent? A negative exponent is equivalent to the inverse of the same number with a positive exponent.
It may only require an intermediate step to complete to make things simpler. The best way to get comfortable with the concept of negative exponents is to work a few example problems that use them. Here are some samples: This works just like solving any other equation. Don't be scared by the fact that the exponent is negative.
Just work it out and remember to "flip over" invert the number if it has a negative exponent. Solve the following for x: You can see a negative exponent, so what's the first thing you might want to do?
I would try to get the exponent to be positive. So, following our definition, just flip over the factor with the negative exponent and make the exponent positive! Remember that when you see a negative exponent you can put it on the other side of the fraction bar and make it a positive exponent.

Scientific Notation Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing , we write x 10 - 9.
