Question

1 stiind ca a=64:4:2 iar b=72:3:6 calculati

axb=
a:b=
a-b=
2x(a+b)=
2x(a-b)=


(axb):(a-b)=
(a:b)x(a+b)=
(axb)-(a:b)=
(axb)-(a+b)=
(a+b):(a-b)=
(a-b)x(a-b)=

Answer 1

a=64:4:2=16:2=8b=72:3:6=24:6=4axb= 8x4=32
a:b= 8 :4 = 2
a-b= 8-4= 4
a+b=8+4=12
2x(a+b)=2x(8+4)= 2x12= 24
2x(a-b)=2x4=8
(axb):(a-b)= 32:4=8
(a:b)x(a+b)=2x12=24
(axb)-(a:b)=32-2=30
(axb)-(a+b)= 32-12=20
(a+b):(a-b)=12:4=3
(a-b)x(a-b)= 4x4=16

Answer 2

a=8  b=4
0)8+4=12
1)8*4=32
2)8:4=2
3)8-4=4
4)2(8+4)=2*12=24
5)2(8-4)=2*4=8
6)(8*4):(8-4)=32:4=8
7)(8:4)*(8+4)=2*12=24
8)(8*4)-(8:4)=32-2=30
9)(8*4)-(8+4)=32-12=20
10)(8+4):(8-4)=12:4=3
11)(8-4)*(8-4)=4*4=16
