Question

Rationalize y²÷x+root x²+y²

Answer 1

Answer :

Now,

y²/{x + √(x² + y²)}

We rationalise the denominator by multiplying both the numerator and denominator by
{x - √(x² + y²)}.

So,

y²/{x + √(x² + y²)} × [{x - √(x² + y²)}/{x - √(x² + y²)}]

= y²{x - √(x² + y²)} × 1/[{x + √(x² + y²)}{x - √(x² + y²)}]

= y²{x - √(x² + y²)}/[x² - (x² + y²)]

= y²{x - √(x² + y²)}/( - y²)

= - {x - √(x² + y²)}
