If A=1+r^a+r^2a+r^3a+.......................to infinity

B=1+r^b+r^2b+................to infinity

then find a/b=?????

Is r^2a supposed to be r^(2a) or a*r^2? In other words, is the a part of the exponent?

what the heck is that?

exponents are like 2 cubed or 2 squared.

2 cubed= 8

2 squared= 4

exponents are like 2 cubed or 2 squared.

2 cubed= 8

2 squared= 4

because cubed means three, and squared means two. so 2 squared would be 2*2=4 and two cubed would be 2*2=4*2=8.
