a = 2+5x3²

b = 7-3^3x5

c = -4²+5x3

d = (-4)²+5x3

e = (-2)^3-(-3)^3

f = -2^4-(-2)^3-(-2)²

Où j'en suis dans mon devoir

a = 2+5x3²
a = 2+(5x3²)
a = 2+(5x9)
a = 2+45
a = 47

b = 7-3^3x5
b = 7-(3^3x5)
b = 7-(27x5)
b = 7-135
b = -128

c = -4²+5x3
c = -4²+(5x3)
c = -4²+15
c = -16+15
c = -1

d = (-4)²+5x3
d = (-4)²+(5x3)
d = 16+15
d = 31

e = (-2)^3-(-3)^3
e = -8+27
e = 19

f = -2^4-(-2)^3-(-2)²
f = -16+8-4
f = -12
