Q: What is 10 to the first power?
Q: What is 10 to the zero power (100)?
The elements of an "exponential expression" are
the base is "raised to the power of" the exponent.
A simple way of thinking about powers of ten is that the exponent indicates the number of zeros:
Tip: It may be more useful for you to think of powers of ten in terms of "zero-places" rather than just "zeros"-- this allows you to use the concept for negative exponents (10-1=0.1) and 'scientification notation' (see following section).
Exponentiation in "Scientific notation"
Exponentiation is used in scientific notation to abbreviate large numbers.
For example, instead of writing 123,000,000,000 , you could write 1.23 x 1011 or 1.23 x (10^11)
The 'Exp' button seen in the image above indicates this type of abbreviation. This can be written as
A simple way of speaking about this notation is to say "move the decimal over 11 places":
Or, if it's a whole number, you could just think of it as adding eleven zeros.
Note that the "exponentiation"/"scientific" notation for the example used on the first part of this page (ten raised to the ninth power) is 1.e+9 .
