Tolong bantu dijawab ya kkyg paling blkng itu a+(b+c)
Penjelasan dengan langkah-langkah:
a = 1, b = -6, c = -11
• a + b = 1 + (-6) = -5
• b + a = -6 + 1 = -5
• (a + b) + c = (1 + (-6)) + (-11) = -5 + (-11) = -16
• a + (b + c) = 1 + (-6 + (-11)) = 1 + (-17) = -16
a = 2, b = 7, c = -12
• a + b = 2 + 7 = 9
• b + a = 7 + 2 = 9
• (a + b) + c = (2 + 7) + (-12) = 9 + (-12) = -3
• a + (b + c) = 2 + (7 + (-12)) = 2 + (-5) = -3
a = 3, b = 8, c = 13
• a + b = 3 + 8 = 11
• b + a = 8 + 3 = 11
• (a + b) + c = (3 + 8) + 13 = 11 + 13 = 24
• a + (b + c) = 3 + (8 + 13) = 3 + 21 = 24
a = -4, b = 9, c = 14
• a + b = -4 + 9 = 5
• b + a = 9 + (-4) = 5
• (a + b) + c = (-4 + 9) + 14 = 5 + 14 = 19
• a + (b + c) = -4 + (9 + 14) = -4 + 23 = 19
a = -5, b = -10, c = 16
• a + b = -5 + (-10) = -15
• b + a = -10 + (-5) = -15
• (a + b) + c = (-5 + (-10)) + 16 = -15 + 16 = 1
• a + (b + c) = -5 + (-10 + 16) = -5 + 6 = 1
