Question

Найдите значения выражений:
а) 2³ + 2.6 =
б) 0.3 + 1.1 =
в) (1.6 - 0.7)² =
г) (0.6×0.5×0.7)³=

Answer 1

а) 2³ + 2.6 =(2•2•2)+2,6=8+2,6=10,6
б) 0.3 + 1.1 =1,4
в) (1.6 - 0.7)² =(1.6 - 0.7)•(1.6 - 0.7)=0,9•0,9=0,81
г) (0.6×0.5×0.7)³=(0.6×0.5×0.7)•(0.6×0.5×0.7)•(0.6×0.5×0.7)=
=0,21•0,21•0,21=0,009261
