Question

Doar punctul f si h. Cat se poate de repede. Cerinta este efectuati. ​

Answer 1

Răspuns:

f) 3.5²+1,2•{11+1,1•[6,5+2•(0,45-0,05]}= =3,5²+1,2•{11+1,1•6,5+2•0,05]}

=3,5²+1,2•{11+1,1•6,5+0,1}

=269/20•{11+1,1•6,6}

=269/20•{11+7,26}

=269/20•18,26=245597/1000

h) [(3,15+4,05)•36,9):[(17,5-10,3)•0,41]=

=[7,20•36,9]:[7,2×0,41]

=265,68:2,952

=9
