Решение:
- а) (3,3)² + (-0,3)³
- \[ (3.3)^2 + (-0.3)^3 = 10.89 + (-0.027) = 10.89 - 0.027 = 10.863 \]
- б) (-1/4)³ - (3/4)³
- \[ igg(-rac{1}{4}igg)^3 - igg(rac{3}{4}igg)^3 = -rac{1}{64} - rac{27}{64} = rac{-1 - 27}{64} = rac{-28}{64} = -rac{7}{16} \]
- в) (-0,3 + 0,2)²
- \[ (-0.3 + 0.2)^2 = (-0.1)^2 = 0.01 \]
- г) (-1/6 + 5/6)³
- \[ igg(-rac{1}{6} + rac{5}{6}igg)^3 = igg(rac{-1 + 5}{6}igg)^3 = igg(rac{4}{6}igg)^3 = igg(rac{2}{3}igg)^3 = rac{8}{27} \]
Ответ: а) 10,863; б) -7/16; в) 0,01; г) 8/27.
