Răspuns

Explicație pas cu pas:

a)   85 - 10 : ( 73 - 8 x 9 ) = 75

= 85 - 10 : ( 73 - 72 ) =

= 85 - 10 : 1 =

= 85 - 10 =

= 75

c)    [ ( 25 + 5 ) x 18 - 170 ] : 10 = 37

= ( 30 x 18 - 170 ) : 10 =

= ( 540 - 170 ) : 10 =

= 370 : 10 =

= 37

d)  ( 12 x 12 + 12 : 12 ) x 12 = 1 740

= ( 144 + 1 ) x 12 =

= 145 x 12 =

= 1 740

__________________________

e)   [ ( 609 : 3 + 72 : 3 ) x 3 - 75 x 8 ] x 2 + 0 : 9 = 162

= [ ( 203 + 24 ) x 3 - 600 ] x 2 + 0 =

= ( 227 x 3 - 600 ) x 2 =

= ( 681 - 600 ) x 2 =

= 81 x 2 =

= 162

Corectie:  69 : 23 NU 69 : 13

f)  3 x [ 90 : 45 + 2 x  ( 69 : 23 + 10 ) ] + 105 : 3 = 119

= 3 x [ 2 + 2 x ( 3 + 10 ) ] + 35 =

= 3 x ( 2 + 2 x 13 ) + 35 =

= 3 x ( 2 + 26 ) + 35 =

= 3 x 28 + 35 =

= 84 + 35 =

= 119

g)  105 - 2 x [ 11 + 5 x 3 - ( 4 + 8 ) ] = 77

= 105 - 2 x ( 11 + 15 - 12 ) =

= 105 - 2 x 14 =

= 105 - 28 =

= 77

h )   26 + 360 : ( 3 x 50 x 5 : 750 ) = 386

= 26 + 360 : ( 750 : 750 ) =

= 26 + 360 : 1 =

= 26 + 360 =

= 386

i)  { 8 + 12 x [ 1000 - 75 : 25 x ( 198 : 3 : 2 ) ] } : 4 = 2 705

= { 8 + 12 x [ 1 000 - 3 x ( 66 : 2 ) ] } : 4 =

= [ 8 + 12 x ( 1 000 - 3 x 33 ) ] : 4 =

= [ 8 + 12 x ( 1 000 - 99 ) ] : 4 =

= ( 8 + 12 x 901 ) : 4 =

= ( 8 + 10 812 ) : 4 =

= 10 820 : 4 =
