Answer 1

Răspuns:

35(43+57)

35×100=3500

721(240+760)

721×1000=721 000

4(35+676)

4×711=2844

33(44+55×99)

33(44+5445)

33×5489=181 137

51(27×34-60)

51(918-60)

Answer 2

Explicație pas cu pas:

35×43+35×57 = 35×(43+57) = 35×100 = 3500

721×240+760×721 = 721×(240+760) = 721×1000 = 721000

4×35+4×52+4×13 = 4×(35+52+13) = 4×100 = 400

33×44+55×33-33×99 = 33×(44+55-99) = 33×0 = 0

27×51+51×34-60×51 = 51×(27+34-60) = 51×1 = 51
