Lesson 2 of 13
Use whole numbers to denote powers of 10. Explain patterns in the number of zeros when multiplying any powers of 10 by any other powers of 10.
a. How many do you see? How do you see them?
b. Instead of writing $$10 \times 10$$, we can write $$10^2$$, which we read “ten to the power of two.” The two is the exponent and tells us how many times we multiply 10 by itself. How would you represent the number of the smallest spokes in the image above as a power of 10?
