Oblicz [(37-31)*(42:6)]-7*2do potegi drugiej= 7+3*[(15-3 do potegi drugiej *2:6):4]= 4 do potęgi drugiej+2*5-[10:(2+3)]= (7*3-3 do potęgi drugiej)*2+2 do potegi trzeciej-9:3

[(37 - 31) * (42 : 6)] - 7 * 2² = (6 * 7) - 7 * 4 = 42 - 28 = 14 7 + 3 * [(15 - 3² * 2 : 6) : 4] = 7 + 3 * [(15 - 9 * 2 : 6) : 4] = 7 + 3 * [(15 - 18 : 6) : 4] = 7 + 3 * [(15 - 3) : 4] = 7 + 3 * (12 : 4) = 7 + 3 * 3 = 7 + 9 = 16 4² + 2 * 5 - [10 : (2 + 3)] = 16 + 10 - (10 : 5) = 26 - 2 = 24 (7 * 3 - 3²) * 2 + 2³ - 9 : 3 = (21 - 9) * 2 + 8 - 3 = 12 * 2 + 5 = 24 + 5 = 29
