The last term approaches zero as n approaches infinity so the fuction approaches 2.

9+23=32
He had 32 CDs to begin with
One way to solve this is to revert to integers.
Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)
Now you have 1,300,000 & 680000. Subtract to get 620,000.
Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5
We have 6.2 x 10^5.
It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
