Question

Write the rationalising factor of 1/3-√11.

Answer 1

Answer:

- (3+√11)/2

Step-by-step explanation:

Given,

Root 1/(3-√11)

To Find,

The rationalising factor.

Now,

Multiplying both numerator and denominator by (3+√11) we get

1/(3-√11) X (3+√11)/(3+√11)

= (3+√11)/(3²-√11²)

= (3+√11)/9-11

= - (3+√11)/2

Hence, - (3+√11)/2 is the answer.
