zadanie ósme wyrażenia algebraiczne i ich wartości liczbowe
a jak ktoś umie to szóste
a (1/3 *6 - 4) ^2 - 6(1/2*6 -1)^2 = 4 - 24 = -20
b 0,5 * -2^2 ( 4* 1^3 - 5) = 2* -1 = -2
c 8 -1^3 + (-2^2 + 6) : 8 = -8 + 10/8 = -6 1/4
d 4+ -1/4 - ( 5* 0,04 -8 ) = -1 - 7 24/25 =-8 24/25
e 3* 1/27 + 2 [ 1/9 - 3(2/3 - 1) ] = 1/9 + 16/9 = 17/9
F) ( 16* 1/16 -2 ) : (2,1 -6,4 * 1/64) + 1/4 = -2 : ( 2,1 - 0,1) +1/4 =-2: 2 +1/4 = -1 + 1/4 = 3/4
