Answer 1

Hey! =)

Răspuns:

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+(4544-1645)=

=1320+2899=

=4219

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

=2307+{3702+[90+3•(1400-690)=

=2307+[3702+(90+3•710)]=

=2307+(3702+2220)=

=2307+5922=

=8229

c) 31975+200•[8•(1270-2•350)+2340:5]=

=31975+200•[8•(1270-700)+2340:5]=

=31975+200•(8•570+2340:5)=

=31975+200•(4560+468)=

=31975+200•5028=

=31975+1005600=

=1037575

Sper că este corect și că te-am ajutat! ^^
