1. Algebra 2 C.C. 1.1 Apply Laws of Exponents
A pet store raises mice for sale. The owner starts with 2 mice. The mice will reproduce in a manner so that the total population of the mice doubles every month. Complete the table below showing the total number of mice.
How many mice will there be after 15 months?
Definition of Powers bx = b ∙ b ∙ b ∙ b ∙ b ∙ b … x factors of b b is the base x is the exponent
Month number
Total population 1 2 3 4 5 6 7
