Question

a.) a= [(15-2-5) 7+25]: 4 - 100: 2; b.) b = 360: {3-2² + [3-23 + (12+3.42): 2²] - 15} - 4; c.) Comparați pe a cu b.​

Answer 1

a = - 33,8

b = - 244

a > b

Răspuns:

a = [ ( 15 - 2 - 5 ) × 7 + 25 ] : 5 - 100 : 2

a = ( 8 × 7 + 25 ) : 5 - 50

a = ( 56 + 25 ) : 5 - 50

a = 81 : 5 - 50

a = 16,2 - 50

a = - 33,8

b = 360 : { 3 - 2² + [ 3 - 23 + ( 12 + 3 × 42 ) : 2² ] - 15 } - 4

b = 360 : { 3 - 4 + [ - 20 + ( 12 + 126 ) : 4 ] - 15 } - 4

b = 360 : [ 3 - 4 + ( - 20 + 138 : 4 ) - 15 ] - 4

b = 360 : ( 3 - 4 + 29/2 - 15 ) - 4

b = 360 : ( - 16 + 29/2 ) - 4

b = 360 : [ ( - 32 + 29)]/2 - 4

b = 360 : ( - 3/2 ) - 4

b = - 360 : 3/2 - 4

b = - 360 × 2/3 - 4

b = - 120 × 2 - 4

b = - 240 - 4

b = - 244

a > b
