dotrungduckid $(-0,02)^{5}= (-2.10^{-2} )^{5} = (-2)^{5} . ( 10^{-2} )^{5} = -32.10^{-10}$
$(-30)^{2}. (-0,05)^{3} \\ =(-3.10)^{2}. (-5. 10^{-2})^{3} \\ = (-3)^{2} .10^{2} .(-5)^{3}.(10^{-2} )^{3} \\ =9 .10^{2} .(-125)}.(10)^{-6} =-1125.10^{-4}$
$(0.001)^{4} .( -0,4)^{3} \\ = ( 10^{-3} )^{4}.(-4. 10^{-1})^{3} \\ = 10^{-12}.(-4)^{3} .( 10^{-1} )^{3} \\ =-64.10 ^{-12}.10^{-3} \\ =-64.10^{-15}$
