Question

Exercitiul 4 si 6 repedeeeee

Answer 1

(7503:61+877):500+53•11=

(123+877):500+583=

1000:500+583=

2+583=585

b) 207•9-(19^2+3^2):74+2296:41=

1863-(361+9):74+56=

1863-370:74+56=

1863-5+56=

1858+56=1914

c) 5•230-7(512:32+2^2)+4687:43=

1150-(16+4)+109=

1150-20+109=

1130+109=1239

d) [493:17-(128:2^3+224:8):22]:27-1=

[29-(128:8+28):22]:27-1=

[29-(16+28):22]:27-1=

[29-44:22]:27-1=

(29-2):27-1=

27:27-1=

1-1=0

a=6+8•[32:4-5(4^3-7•3^2)]

a=6+8[8-5(64-7•9)]

a=6+8[8-5(64-63)]

a=6+8(8-5•1)

a=6+8•3

a=6+24

a=30

b=15•2+(256:16+4):5+2121:21

b=30+(16+4):5+101

b=30+20:5+101

b=30+4+101

b=34+101

b=135
