Bună! ⭐

_________

$a) (\sqrt{2} )^{3} *(\sqrt{2} )^{2} =2\sqrt{2} *2=4\sqrt{2}$

$d) (-\frac{\sqrt{5} }{7} )^{-5} *(-\frac{\sqrt{5} }{7} )^{6} =(-\frac{\sqrt{5} }{7} )^{-5+6} =(-\frac{\sqrt{5} }{7} )^{1} =-\frac{\sqrt{5} }{7}$

$g) (^{\sqrt{3}) } \frac{2}{\sqrt{3} } )^{3} :(^{\sqrt{3} )} \frac{4}{\sqrt{3} } )^{3} =(\frac{2\sqrt{3} }{3} )^{3}: (\frac{4\sqrt{3} }{3} ) ^{3} =\frac{(2\sqrt{3} )^{3} }{3^{3} } *\frac{3^{3} }{(4\sqrt{3} )^{3} } =8*3\sqrt{3} *\frac{1}{64*3\sqrt{3} } =\frac{1}{8}$
