Răspuns:
a = 26
b = 72
3⋅a - b:2 = 42
Explicație pas cu pas:
a = {275 : 25 ⋅ 8 – [390 – (56 ⋅ 4 + 116)]} : 2 + 10
a = {88-[390-(224+116)]}:2+10
a = [88-(390-340)]:2+10
a = (88-50):2+10
a = 38:2+10
a = 16+10
a = 26
b = 200 – 4 ⋅ {4 ⋅ [4 ⋅ (6 + 2) - 132 : 11] : 5 ⋅ 2}
b = 200-4⋅[4⋅(4⋅8-12):5⋅2]
b = 200-4⋅[4⋅(32-12):5⋅2]
b = 200-4⋅(4⋅20:5⋅2)
b = 200-4⋅(80:5⋅2)
b = 200-4⋅(16⋅2)
b = 200-4⋅32
b = 200-128
b = 72
26⋅3-72:2 =
= 78-36
= 42
