Question

If the quantity 4 times x times y cubed plus 8 times x squared times y to the fifth power all over 2 times x times y squared is completely simplified to 2xayb + 4xcyd, where a, b, c, and d represent integer exponents, what is the value of a? _______

Answer 1

(4xy^3+8x^2y^5)/(2xy^2)  Since 2xy^2 is a common factor we have

2y+4xy^3

2y=2x^ay^b

x^0=x^a

a=0
