Question 67015
a to the 10 power divided by a to the 7 power

how do i solve this?


a^10=a*a*a*a*a*a*a*a*a*a
---- -----------------------------
a^7= a*a*a*a*a*a*a


Now we can start cancelling a's and when we are finished, we will have a*a*a in the numerator so our answer is:

a^10
----=a^(10-7)=a^3
a^7

When you divide, you subtract exponents.  When you multiply, you add them.
