Simplify the following expression, and rewrite it in an equivalent form with positive exponents. 15x^4y/17x^2y7
A. 3x^2/y^6 B.3x^2/y^6 C.3x^6y^8 D. 52x^2/y^6

there is not much you can do with 15/17
put numerator and denominator in parentheses
do you mean y^7 in denominator? 
i have to choose ab or c

Well, Look at what you typed. No way anything with 15 in the numerator and 17 (a prime number) in the denominator is going to come out to a b c or d.
You have a mistake or your book has a mistake. 
51x^4y/17x^2y^7

I think its A

Thank you for the 51 instead of the 15
Now you know the correct answer has to start with 51/17 which is 3
x^4/x^2 = x^2
so far
3 x^2
now y/y^7 = 1/y^6
so in the end
3 x^2 / y^6
which is
A
