What is the rule for multiplying powers with the same base?

Back

When multiplying powers with the same base, add the exponents. For example, a^m * a^n = a^(m+n).

What is the rule for dividing powers with the same base?

Back

When dividing powers with the same base, subtract the exponents. For example, a^m / a^n = a^(m-n).

What does a zero exponent mean?

Back

Any non-zero base raised to the power of zero equals one. For example, a^0 = 1.

How do you express a number with a negative exponent as a fraction?

Back

A number with a negative exponent can be expressed as the reciprocal of the base raised to the positive exponent. For example, a^-n = 1/(a^n).
