Question

rationalize the denominator of following 7/5√3-5√2​

Answer 1

Answer:

$\frac{7}{5 \sqrt{3} - 5 \sqrt{2} } = \frac{7}{5} ( \frac{1}{ \sqrt{3} - \sqrt{2} } \times \frac{ \sqrt{3} + \sqrt{2} }{ \sqrt{3} + \sqrt{2} } ) = \frac{7}{5} \times \frac{ \sqrt{3} + \sqrt{2} }{3 - 2} = \frac{7}{5} ( \sqrt{3} + \sqrt{2} )$
