Question

racionalize os denominadores a)1/√10= b)3/2√3= me ajudem por favor

Answer 1

$\dfrac{1}{ \sqrt{10}} \\ \\ \\ \dfrac{1.(\sqrt{10})}{ (\sqrt{10}) . (\sqrt{10})} \\ \\ \\ \dfrac{(\sqrt{10})}{ (\not \sqrt{10})^ \not 2} \\ \\ \\ =\ \textgreater \ \dfrac{\sqrt{10}}{ 10 }$


===

$\dfrac{3}{2 \sqrt{3} } \\ \\ \\ \dfrac{3 ,(2 \sqrt{3})}{(2 \sqrt{3}).(2 \sqrt{3}) } \\ \\ \\ \dfrac{3 ,(2 \sqrt{3})}{(2 \sqrt{3})^2} } \\ \\ \\ \dfrac{6 \sqrt{3}}{4. 3} } \\ \\ \\ \dfrac{6 \sqrt{3}}{12} } \\ \\ \\ =\ \textgreater \ \dfrac{ \sqrt{3} }{2}$
