a) 1/ 4×3² - 6×10 = 4×9 - 6×10 = 36 - 60 = -24
2/ 4× (3²- 6 × 10) = 4× (9 - 60) = 4 × (-51) = -204
3/ 4× (3² - 6 ) ×10 = 4×3×10 = 120
b) 1/ 3 - 5²×2 + 8 = 3 - 25×2 + 8 = 3 - 50 + 8 = -39
2/ (3 - 5²)×2 + 8 = (3 - 25)×2 + 8 = -22×2 + 8 = -36
3/ 3 - 5²×(2 + 8) = 3 - 25×10 = 3 - 250 = -247
Bonsoir
4 x 3^2 - 6 x 10
= 4 x 9 - 60
= 36 - 60
= -24
4 x (3^2 - 6 x 10)
= 4 x (9 - 60)
= 4 x (-51)
= -204
4 x (3^2 - 6) x 10
= 4 x (9 - 6) x 10
= 4 x 3 x 10
= 120
3 - 5^2 x 2 + 8
= 3 - 25 x 2 + 8
= 3 - 50 + 8
= -39
(3 - 5^2) x 2 + 8
= (3 - 25) x 2 + 8
= (-22) x 2 + 8
= -44 + 8
= -36
3 - 5^2 x (2 + 8)
= 3 - 25 x 10
= 3 - 250
= -247
