Question

racionalize os denominadores de 8/10+ raiz de 3​

Answer 1

$\frac{8}{10 + \sqrt{3} } = \frac{8}{(10 + \sqrt{3})} \times \frac{(10 - \sqrt{3}) }{(10 - \sqrt{3} )}$

$\frac{8 \times (10 - \sqrt{3})}{ {10}^{2} - { \sqrt{3} }^{2} } = \frac{8 \times (10 - \sqrt{3})}{100 - 3} = \frac{8(10 - \sqrt{3}) }{97}$
