1/3+√2 , Rationalise the denominators of the given numbers.

Answer» \bold{Answer :}

To rationalize the DENOMINATOR of the given number, we MULTIPLY both the numerator and the denominator by the conjugate irrational number (3 - √2)

Now, 1/(3 + √2)

= (3 - √2)/{(3 + √2)(3 - √2)}

= (3 - √2)/(9 - 2)

= (3 - √2)/7,

which is the REQUIRED form
