Mid-terms are over, US elections are over, Halloween is over. As winter approaches, it's time to start thinking about next semester. Sure, this semester has some life left in it yet, so don't lose sight of that. Still, you'd better start mapping out your spring and summer semesters to make sure you get the courses you want (or need).

Read moreAsk Professor Cram: Expanding a Rational Expression
Dear Professor Cram:
I am taking a distance learning college algebra course, so I am left on my own to some extent to learn the material. I'm just beginning to work problems like: (5x²/6y²)³
The book I'm using doesn't give me an example of this type of problem. Where do I start?
Marilyn D., Lancaster, CA
Thank you for using College-Cram.com and for your Algebra question.
The best way to expand this rational expression is to recall that raising anything to the power of three means to multiply it by itself three times:

Dear Professor Cram:
I have a question about series circuits. There are 3 resistors, R1 is 10kohms/.5W and R2 is 3.3kohms/.250W and the third is unknown. If the circuit draws a current of 1.5mA from a 27V source, how do i calculate the ohmic value of the third resistor?
Nicholas, Mohawk College
Thank you for your question, Nicholas. Physics is not normally my forte, but I can certainly help you with this one. Our first step is to determine the power and resistance for the circuit as a whole:
