What is y?
1. X is an integer
2. Y is an integer
How do i approach this question?
x^3y^4=2*2^3*5^3 ---> x^3*y^4=2^4*5^3.
Now X and y could be non integers so we cant say for certain y^4=2^4.
S1: X=integer. X could be 1 and y^4 could equal the 4th root of 2000. insuff. Or x can be 5 and Y 2
S2: Same thing Y could be 1 or 2.
Together we cannot have either as the 4throot of 2000. So Y must be 2
