There are also rules for combining exponents (also called the laws of indices):

• To multiply exponents with identical bases, add the exponents, such as 3² × 3³ = 3⁵ (3 is the base).
• To multiply like exponents, combine terms, such as 10² × 2² = (10 × 2)² = 400.
• To divide identical bases, subtract the exponents, such as 103/10 = 10^3-1 = 10² = 100 (the denominator 10 has an assumed exponent of 1).
