Step-by-step explanation:

We rationalize the denominator of the given number by multiplying both its numerator and its denominator by the conjugate irrational number (√7 - √5)

Now,

(√7 - √5)/(√7 + √5)

= {(√7 - √5) (√7 - √5)}/{(√7 + √5) (√7 - √5)}

= (7 - 2√35 + 5)/(7 - 5)

= (12 - 2√35)/2

= 6 - √35,

which is the required form
