I worked on this problem (see here: http://ift.tt/1j2MQQa #35),
and I got the answer as B. I checked the solutions, and it says invalid.
Could anyone clarify why it is invalid?
Never mind, I am silly and now I see why it's invalid----- they excluded the last part of the equation from the exponent. Maybe they are the silly ones.
