Bună!

=3

14.

a) 1320+[48•23+(340•11-60•5)-235•7]=

=1320+[48•23+(3740-300)-235•7]

=1320+(48•23+3440-235•7)

=1320+(1104+3440-1645)

=1320+(1104+1795)

=1320+2899

=4219

b) 2307+{3702+[270÷3+3•(280+5-3•230)]}=

=2307+{3702+[270÷3+3•(280+460)]}

=2307+[3702+(270÷3+3•740)

=2307+[3702+(90+2220)

=2307+(3702+2310)

=2307+6012

=8319

c) 31.975+200•[8•(1270-2•350)+2340÷5]=

=33.975•[8•(1270-700)+2340÷5]

=33.975•(8•570+468)

=33.975•(4460+468)

=33.975•4928

=.... (calculezi tu singur/ă)

15.

a) 785+115+37•(15+23•12)=

=900+37•(15+276)

=937•291

=.... (calculezi singur/ă)
