This document is from a lesson on multiplying numbers in exponential notation. It reviews the rule that when multiplying numbers with the same base, you add the exponents. Examples are provided like 53 × 58 = 511, demonstrating how to combine like bases by adding the exponents. The lesson emphasizes you can only simplify when the bases are the same, otherwise you must leave the expression as is. It concludes by asking how to explain this process of multiplying exponential expressions to an absent student.

Write this down!
When bases are alike- ADD the exponents
xm
xn
= xm+n

Can ONLY simplify when the bases are the
same!!!
If they are not the same, you have to leave
them alone!
