Question

Scrie trei exerciti cu fractii zecimale (exemplu: 2,56 : 1,6 + 2,5 x [0,5 la puterea a doua - 0,7 : 10 + 10 x (13-12,6) ) REPEDE

Answer 1

1).

(2,4•1,2-29:100+7,8 la puterea a doua)•18:2,5=

=(2,88-0,29+60,84)•7,2=

=(2,59+60,84)•7,2=

=63,43•7,2=456,696

2).

62:10-0,02•1,3+28,5•2,2 la puterea a doua=

=6,2-0,026+28,5•4,84=

=6,174+137,94=144,114

3).

(29:100+3,7•4-123:100) totul la puterea a doua=

=(0,29+14,8-1,23) la a doua=

=13,86 la a doua=

=192,0996
