\(6\cdot 4^2=96\)
\(40\cdot30-9\cdot6=1146\)
\(810\cdot\left(\frac12\right)^3=101{,}25\)
\(h=8\sin30^\circ=4\), \(S=\frac{10+20}{2}\cdot4=60\)
\(\left(\frac93\right)^2=9\)
\(\frac{9{,}6}{1{,}3-1{,}6}=-32\)
\(400+400\cdot0{,}25=500\)
\(\sin\alpha=-\sqrt{1-\frac{24}{25}}=-0{,}2\)
\(4-5x=9 \Rightarrow x=-1\)
