\huge\mathfrak\pink{Given:}

\frac{√3 + 1}{√3 – 1} = \frac{a + b}{√3} \\

\huge\mathcal\color{Lime}FIND:

value of. (a + b√3).

\mathcal\color{Lightpink}rationalizing\: denominator

\frac{√3 + 1}{√3 - 1} = \frac{√3 + 1}{√3 + 1}

\huge\mathrm\orange{By\:using\:formula\:}

\pink{★(a + b)²\:= \: a² + 2ab + b²★}

\pink{★(a + b) (a – b) \:= \: a² – b²★}

\frac{(√3)² + 2(√3)(1) + (1)²}{(√3)² - (1)²} \\

\frac{3 + 2√3 + 1}{3 - 1} \\

\frac{4 + 2√3 }{2} \\

\frac{2 + (2√3 )}{2} \\

⇒ 2√3

★ a = 1 & b = 1 ★
