Here in this question, concept of rationalisation is used. We see that we are given a fraction with denominator as irrational number. So firstly we will rationalise it and will compare it with another given equation to find value of a and b.
So let's do it!!
___________________________
Given equation is::
Let's consider LHS!
Now multiplying 4+√7 on both numerator and denominator to rationalise it::
Now multiplying it::
Now applying algeberic identities :-
• (A+B)²=A²+B²+2AB
• (A+B)(A-B)=A²-B²
Now solving it::
By comparing it with RHS, we get::
Hence we obtained the values of a and b.
