Question

Which of the following would result in ?
3x^2
A.3xy divide xy
b. 7 x^y - 4x^2y
c. xy+2xy
D.18x^3y^2/6xy^2

Answer 1

A would result in 3 because the x and the y would cancel out.
B stays the same because the exponents on the variables are different (x is different than x^2)
C Would result in 3xy (you just add the numbers if the exponents are the same)
D Would result in 3x^2 (the 18/6 = 3 ) (x^3/x = x^2) and (y^2/y^2 cancels out)

Answer 2
