Question

rationalise 2+√3-1/2+√3​

Answer 1

Answer:

$\tt \huge {\red{ \fbox { - 2}}}$

Step-by-step explanation:

$\huge \frac{2 + \sqrt{3 } - 1}{2 + \sqrt{3} } \times \frac{2 - \sqrt{3} }{2 - \sqrt{3} } \\ \\ \huge = \frac{2( \sqrt{3} - \sqrt{3} - 1)}{ {(2)}^{2} - {( \sqrt{3} )}^{2} } \\ \\ \huge = \frac{2 \times - 1}{4 - 3} \\ \\ \tt \huge = \frac{ - 2}{1} = - 2$
