Rationalise the denominator of the
following
3
13-1​

Answer 1

Answer:

so I think you mean 3/√13-1 if yes then here it's-;

3/√13-1×√13+1/√13+1

3√13+3/(√13)²-1²

3√13+3/13-1

=> 3√13+3/12

in case you didn't get what I mean-:

3.

√13-1

3×√13+1.

√13-1×√13+1

3√13+3.

(√13)²-1²

3√13+3.

13-1=> 12

ans=> 3√13+3
