Question 18: The result of the calculation \(| – 2|\sqrt {0.25} + {( – 3)^3} \cdot \frac{1}{9} + {( – 2019)^0} \ cdot {( – 1)^{2019}}\) is
\(| – 2|\sqrt {0.25} + {( – 3)^3} \cdot \frac{1}{9} + {( – 2019)^0} \cdot {( – 1)^{ 2019}} = 2 \cdot \sqrt {0,{5^2}} + \frac{{ – 27}}{9} + 1 \cdot ( – 1) = 2.0.5 – 3 – 1 = 1 – 3 – 1 = – 3\)
