Question

rationalise the denominator of 2/root3-root4​

Answer 1

Answer:

Step-by-step explanation:

2/root3-root4

So we will multiply it with root3+root4 , inorder to make it look like the identity (a+b)(a-b)=a^2-b^2.WE ALSO HAVE TO MULTIPLY IT IN THE NUMERATOR,AS BECAUSE IT IS EQUIVALENT FRACTION

ACCORDING TO PROBLEM :-

or , 2(root3+root4)

    ____________________

     (root3-root4)(root3+root4)

or,   2root3+2root4    

     ________________

     (root3)^2 - (root4)^2

or,    2root3+2root4    

     ________________

            3 - 4

or, 2root3+2root4    

     ________________

               - 1

or, -2root3 -2root4 (ANSWER)
