$\frac{7}{ \sqrt{3}- \sqrt{2} }$

Answer 1

$\frac{7}{ \sqrt{3} - \sqrt{2} } . \frac{ \sqrt{3}+ \sqrt{2} }{ \sqrt{3} + \sqrt{2} }$

$\frac{7 \sqrt{3} + 7 \sqrt{2}}{3-2 }$

$7 \sqrt{3}+7 \sqrt{2}$

Answer 2

racionalizar

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

$\frac{7( \sqrt{3} + \sqrt{2}) }{ \sqrt{3^2} - \sqrt{2^2} } = \frac{7( \sqrt{3}+ \sqrt{2} ) }{3-2} =$

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