Question

$(3 - \sqrt3 ) \div 5 \times( 3 + \sqrt3) \div 5$
please answer

Answer 1

$\frac{3 - \sqrt{3} }{5} \times \frac{3 + \sqrt{3} }{5} \\ \\ \\ \\ => \frac{(3 - \sqrt{3})(3 + \sqrt{3}) }{25}$


We know, (a - b) (a + b) = a² - b²


$\frac{ {3}^{2} -( { \sqrt{3}) }^{2} }{25} \\ \\ = > \frac{9 - 3}{25} \\ \\ \\ => \frac{6}{25}$
