If y>x>0, which of the following must be true:
I. y^2>x^2
II. y^3 > x^3
III. |y|>x Choose the correct choice from the following choices.
A) I only  B) II only  C) I, II and III  D) II and III  E) III only
Assuming x and y to be integers   X=3,Y=2   X^2=3^2=9   Y^2=2^2=4   So I is true   Now lets look at option III because if option 3 is true E is the answer or else A   As per question X&gt;Y&gt;0 Hence |X| &gt;Y   So OA=I, II and III
<result>C</result>
If y>x>0, which of the following must be true:
I. y^2>x^2
II. y^3 > x^3
III. |y|>x
