Question

find the excat value of and b

I will give brainliest to one who solve it​

Answer 1

LHS

Let

• √3-1 be x
• √3+1 be y

$\\ \rm\Rrightarrow \dfrac{\sqrt{3}-1}{\sqrt{3}+1}+\dfrac{\sqrt{3}+1}{\sqrt{3}-1}$

$\\ \rm\Rrightarrow \dfrac{x}{y}+\dfrac{y}{x}$

$\\ \rm\Rrightarrow \dfrac{x^2+y^2}{xy}$

• Put values

$\\ \rm\Rrightarrow \dfrac{3-2\sqrt{3}+1+3+2\sqrt{3}+1}{3-1}$

$\\ \rm\Rrightarrow \dfrac{8}{2}$

$\\ \rm\Rrightarrow 4$

$\\ \rm\Rrightarrow 4+0\sqrt{3}$

Now

Compare with RHS

• a=4
• b=0
