POZIOM A
a) 4 * 2 - 8 = 8 - 8 = 0
b) [tex]\frac{2}{3*3 - 2} = \frac{2}{9 - 2} = \frac{2}{7}[/tex]
c) [tex]\frac{3^2 +5*3}{6} = \frac{9 +15}{6} = \frac{24}{6} = 4[/tex]
d) 2*4 + [tex]4^2[/tex] = 8 + 16 = 24
e) [tex]2^2 - 2^3 = 4 - 8 = -4[/tex]
f) 3*4 - 1 = 12 - 1 = 11
POZIOM B
a) 5*(-3) + [tex](-3)^2[/tex] = 5*(-3) + 9 = -15 + 9 = -6
b) [tex]\frac{4,5 - 2*(-3)^2}{3} = \frac{4,5 - 2*9}{3} = \frac{4,5 - 18}{3} = \frac{-13,5}{3} = -4,5[/tex]
c) [tex](-2)^2 - (-2)^3 = 4 - (-8) = 4 + 8 = 12[/tex]
d) [tex]3*(-1)^2 + 2*(-1) = 3*1 + (-2) = 3 - 2 = 1[/tex]
e) [tex]\frac{-7}{ 8-4*(-1)} = \frac{-7}{8 - (-4) } = \frac{-7}{8+4} = \frac{-7}{12} = - \frac{7}{12}[/tex]
f) 2(4*(-1) +1) - 5 = 2( -4 + 1) - 5 = 2 * (-3) - 5 = -6 - 5 = -11
