Odpowiedź:
a) 5m + m^2 = -15 +9=-6
b) 4,5 +2b^2 / 3 = 4,5 + 18 / 3 =4,5+6=10,5
c) k^2 - k^3 = 4 + 8 = 12
d) 3x^2 +2x= 3-2=1
e) -7 / 8-4a = -7 / 12
f) 2(4p + 1) - 5 = 2(-4 +1)-5=-8+2-5= -11
g) y(y+3)=y^2+3y=16-12=4
h)3/4(t-2)^2 = 3/4 (t^2 +4) = 3/4 (36 + 4) = 3/4 * 40 = 3/1 * 10 = 30
i) 4z - 2 /11 = -8 - 2/11 = - 8 2/11
