Study this problem on equivalent power of 10, then continue.
100,000,000 = ______
Rule:
to express a whole number as
a smaller number times a
power of 10, move the decimal
point to the LEFT, count the
number of places to the
original point, and use this
count as a POSITIVE exponent
(or power) of 10.
Solution:
Move the decimal point 8
places to the LEFT; the
exponent is a POSITIVE 8.
Thus:
100,000,000 = 1 X 108 = 108
