Answer 2

To prove the given equation:

(A√B - B√A) / (A - B) = AB / (A√B + B√A)

Let's start by using the difference of squares formula:

(A - B)(A + B) = A^2 - B^2

Now, let's try to apply this to the equation:

(A√B - B√A) / (A - B)

Multiply both the numerator and denominator by (A√B + B√A):

[(A√B - B√A) / (A - B)] * [(A√B + B√A) / (A√B + B√A)]

Now, we can apply the difference of squares formula in the denominator:

[(A√B - B√A)(A√B + B√A)] / [(A - B)(A√B + B√A)]

Now, we can simplify further:

A√B * A√B - B√A * B√A / (A - B)(A√B + B√A)

A^2B - AB^2 / (A - B)(A√B + B√A)

Now, let's factor out AB in the numerator:

AB(A - B) / (A - B)(A√B + B√A)

Now, we can see that (A - B) cancels out in the numerator and denominator:

AB / (A√B + B√A)

So, the equation (A√B - B√A) / (A - B) is indeed equal to AB / (A√B + B√A).
