Bonjour

a) 5×5² - 10 + 4×5 = 25 - 10 + 20 = 35

b) -12×2 + 2² + 5 = -24 + 4 + 5 = -15

c) 13 - 10×(-3) + 4×(-3)² = 13 + 30 + 36 = 79

d) 9×4 + 3 - 4×4² = 36 + 3 - 64 = -25

Bonjour;

a)

5*5² -10+4*5

= 5*25 -10+20

=125 +10

= 135

b)

-12*2 +2² +5

= -24 +4 +5

=-15

c)

13 -10*-3 +4*(-3)²

= 13 +30 +4*9

= 13 +30 +36

= 79

d)

9*4 +3 -(4*4²)

36 +3 - 64

= -25
