my teacher failed at explaining this: 3 over 8x^3; y^3 over 9x^7. Find the LCD for the rational expressions and then convert each expression to an equivalent expression with the denominator equal to the LCD; do not reduce fractions.

    It's the last section of the semester that we are not testing on, but the professor is still requiring completion of this section.

    yes. It's subject matter that won't be focused on until next semester, which I think is rather silly. I do have skype, let me check to see if it is installed on my computer though:)
