1] y is positive
statement 1 alone is not sufficient.
y has multiple solutions.

2] x is an integer
x=10 y^4=5
x=1 y^4=5000
statement 2 is not suffcient

combined
not suffcient.

Agree with C if statement 2 is "y is positive integer'

Here statement 2 is "y is positive"
So E is the answer.

Thank you Tiger.

Also, I need clarity with this question. Does the question state:

A) x^3 times y^4

or

B) x to the 3y power to the 4th power?

Thanks again. Looking at it as B makes it much more confusing.
