a) (6,65:10+1,02):100+0,4x(2,6x2,6)-(0,1x0,1x0,1)=
=(0,665+1,02):100+0,4x6,76-0,001=
=1,685:100+0,4x6,76-0,001=
=0,01685+0,4x6,76-0,001=
=0,01685+2,704-0,001=
=2,72085-0,001=
=2,71985
b)0,2x(11,28+0,034x1,55):10+0,6x9-0,0016=
=0,2x(11,28+0,0527):10+0,6x9-0,0016=
=0,2x11,3327:10+0,6x9-0,0016=
=2,26654:10+0,6x9-0,0016=
=0,226654+0,6x9-0,0016=
=0,226654+5,4-0,0016=
=5,626654-0,0016=
=5,625054
