c) 8a^3 + (b^2 + 6) : c dla a=-1, b=-2, c=8
d) 4x - (5y^2 + 8z^3) dla x=-1/4, y=0,2, z=-1
e) 3m^3 + 2[m^2 - 3(2m - 1)] dla m=1/3
f)16z^2 - 2/2,1- 6,4 razy z^3 dla z=1/4
za pierwsza dobra odp daje naj !

c) 8* (-1)^3+ ((-2)^2 + 6) :8 = -8+10 : 8 = -8 + 5/4 = -63/4
d) 4 * (-1/4) - (5*(0,2)^2 + 8*(-1)^3) = -1 - 0,2 +8 = 6,8
e) 3*(1/3)^3 + 2[1/3^2- 3(2*1/3 -1) ] = 1/9 + 2(1/9-3(2/3 -1)) = 1/9 + 2[1/9-2+3]=1/9+2 (1/9+1) = 1/9+2/9+2 = 3/9+2 = 2 i 1/3
f) 16* 1/4^2 - 2/2,1 - 6,4 * (1/4)^3 = 1-2/2,1-6,4*1/64 = 1 - 20/21 - 0,1 = 0,9 - 20/21 = 9/10 - 20/21 = 189/210 - 200/210 = - 11/210
