Question

rationalise the demoninator of 3/4+root 3

Answer 1

Hey friend,
Here is the answer you were looking for:
$\frac{3}{4 + \sqrt{3} } \\ \\ \\ = \frac{3}{4 + \sqrt{3} } \times \frac{4 - \sqrt{3} }{4 - \sqrt{3} } \\ \\ = \frac{3 \times 4 - 3 \times \sqrt{3} }{ {(4)}^{2} - {( \sqrt{ {3)} } }^{2} } \\ \\ = \frac{12 - 3 \sqrt{3} }{16 - 3} \\ \\ = \frac{12 - 3 \sqrt{3} }{13}$

Hope this helps!!!
