Introduction to Exponents

An exponent is a positive integer that indicates repeated multiplication. In the expression ba,the "b" is called the base while the "a" is called the exponent.

This expression is read as "b to the power of a" or "b to the 'a' power," and it means to multiply "b" by itself "a" times.

If "b" is a non-zero real number, then b0 = 1.

If "b" is a non-zero real number, then b1 = b.

Negative Exponents

Negative exponents are a special type of exponent.

If "b" is a non-zero real number and "a" is a positive integer, then b-a = 1/ba.
