# Exponent Arithmetic

Starting points, what the symbols mean : Fractional exponents are a way to represent roots :

If w2 = s, then w = s1/2 That is, a 1/2 exponent is another way to write square root.

The nice thing about exponents is that you can do many calculations without using your
calculator , and in science we express many quantities as powers of ten .

In multiplication , add exponents when the same number (in the case shown, 10) is raised to a power: In division , subtract exponents when the same number (in the case shown, 10) is raised to a power: When raising to a power , multiply. When taking a root , divide as shown below: Problems for practice:
I have intentionally set up the following problems so you could solve them without a
calculator if you apply the rules above. Please try solving these in your head or use a piece of paper.
If you use a calculator , you are defeating the purpose of the exercise. Prev Next
