Your answer :
The rule won’t work in this case.
Courage! The division rule got us through
b 0 , where
m = n , and it will get us through the case where
m is smaller than
n . In this case we have
( b 2 )/( b 3 )
and applying the rule
( b m )/( b n ) b ( m − n )
we get
( b 2 )/( b 3 ) b ( 2 − 3)
So the exponent of our quotient is
( 2 − 3) , which is -1, isn’t it? So just write
( b 2 )/( b 3 ) b ( 2 − 3) b − 1
as if you knew what it meant.
Now return to page 101 and choose the right answer.
