Answer:

A. (x² -y²)² +(2xy)² = (x² +y²)²

Step-by-step explanation:

As is often the case with problems like this, the correct answer (A) is the only answer that is actually a true equation.

Choices B, C, D are only true if x or y is zero--a violation of the given condition that they are positive integers.

Lim->infinity 4n^2/n^2+10000n

dybincka [34]

let P(n)=4n² / n²+10000n
when n ----------> infinity, the main rule is as follow
lim P(n)=4n² / n²+10000n = lim P(n)=4n² / n²= lim 4= 4
n ----------> infinity n ----------> infinity n ----------> infinity
finally

Lim->infinity 4n^2/n^2+10000n = 4
