    The 2x^x is an angle? And the (3 \times 10)^x is the base length?

    I'm sorry, but there isn't much information here and the diagram is hard to read.

    a) Product means to multiply, sum means to add. So your answer is 6xy.

    b) Pd + Mn dollars.

    c) \frac{a + b + c}{3}
    Add all the numbers and divide by the number of numbers.
