\[\textbf{а)}\ 3,44 + (0,9\ :0,45)^{2} - 2,4 \cdot 0,6 =\]

\[= 6\]

\[0,9\ :0,45 = 90\ :45 = 2\]

\[2^{2} = 4\]

\[2,4 \cdot 0,6 = 1,44\]

\[3,44 + 4 - 1,44 = 6\]

\[\textbf{б)}\ (0,7\ :0,35)^{2} - 4,3 \cdot 0,7 + 2,56 =\]

\[= 3,55\]

\[0,7\ :0,35 = 70\ :35 = 2\]

\[2^{2} = 4\]

\[4,3 \cdot 0,7 = 3,01\]

\[4 - 3,01 + 2,56 =\]

\[= 6,56 - 3,01 = 3,55\]

\[0,02\ :0,125 = 20\ :125 = 0,16\]

\[2,84 + 0,16 = 3\]

\[3^{2} = 9\]

\[4,3 \cdot 0,17 = 0,731\]

\[9 - 0,731 = 8,269\]

\[8,269 + 0,658 = 8,927\]

\[0,065\ :0,325 = 65\ :325 = 0,2\]

\[{0,2}^{3} = 0,008\]

\[2,408 - 0,008 = 2,4\]

\[0,084 + 1,916 = 2\]

\[2^{2} = 4\]
