I can't tell from your question where the parentheses start and end, so I'm just guessing: 9 + 4³ x (20 - 8) ÷ 2 + 6 = 9 + 4³ x (12) ÷ 2 + 6 = 9 + 4³ x 12 ÷ 2 + 6 = 9 + (4x4x4) x 12 ÷ 2 + 6 = 9 + 64 x 12 ÷ 2 + 6 = 9 + (64 x 12 ÷ 2) + 6 = 9 + (768 ÷ 2) + 6 = 9 + (384) + 6 = 9 + 384 + 6 = 393 + 6 = 399
2 is prime 4 = 2 x 2 6 = 2 x 3 9 = 3 x 3
6 x 9 / 2 = 27
3 x 3 = 9 2 x 2 x 2 = 8 2 x 7 = 14 2 x 3 = 6
