Odpowiedź:
a) 4 * 2 - 8 = 8 - 8 = 0
d) 2*4 + 4² = 8+16 = 24
f) 3*4-1 = 12-1 = 11
e) 2²-2³= 4-8 =-4
-------------------------------------
a) 5*(-3)+(-3)² = -19+9=-6
d) 3*(-1)²+2*(-1) = 3*1 -2 =3-2=1
c) -2² - (-2)³ = 4 - ( -8) = 4+8 = 12
---------------------------------------------------
b) 3,5*(-5)+5*2 = -17,5 +10 = -7,5
c) 3*6 - 1/2 * (-4) = 18- ( -2) = 18+2 = 20
a) ( 2*5 - ( -3)²) /4 = ( 10-9)/4 = 1/4 = 0,25
