Question 59221
We need to have you type in your problem and directions.  We don't have your book.  I noticed that you put this in the catagory of polynomials and rational expressions.  If you need to raise something to a power: x^2 tells us "x squared".  If you need to type a fraction: x/2+y, means (x divided by 2)+y.  If you want the y to be part of the denominator type it this way:x/(2+y).  Look forward to hearing from you.
Happy Calculating!!!
