1-3 Exponent Riddle
LESSON
CHAPTER
What is the greatest number that can be written with
two digits?
You can write a number in exponential form to show repeated
multiplication. A number written in exponential form has a base
and an exponent. An exponent tells you how many times a number,
called the base, is used as a factor.
Find the value of each expression below. Then in the box at the
bottom of the page, write each expression’s letter in the blank
above its value. When you have found all the values, you will
have solved the riddle.
