Bruno,
You overlooked the question at the bottom of the page that I tried
unsuccessfully to work out. Brent supplied the answer but what I was looking
for were the steps that lead up to the answer. marty

a^n * a^(-m) = a^(n-m)
Again, verify this on simple example of your own.
OK: If a=10 and n=3 and m=4 Following the formula above "a^n *
a^(-m)" ,I get as the first half of the equation:
10^3 * 10/4 = 1000 x 2.5= 2500 but for the second half "a^(n-m)
I get:
10^(n-m)= 10^ -1= 10/1
which of course makes no sense at all. Where did I go wrong?
