Plis pomóżcie.!

Damnaj..:D

Answer 1

 a. ½ * [(-1)⁸+(-1)⁸]= ½*[1+1]=½*2=1

 

b. (-3⅓)³*0,3⁴-(-½)³*(1⅓)²=(-10/3)do potegi 3*0.3do potegi 4 -(-1/2)do potegi 3 *(4/3) do potegi 2= (-1000/27)*81/10000-(-1/8)*16/9= 3/10+2/9=27/90+20/90=47/90

 

c (1 cala 1/3) do potegi 3 *(3 cale i 3/4) do potegi 2:3-(1/3)do potegi 2=

    (4/3)do potegi 3 *(-15/2) do potegi 2:3 -1/9= 64/27*225/16:3 -1/9=14400/432*1/3- 1/9=4800/432-1/9=4800/432-48/432=11

 

wydaje mi sie ze bedzie dobrze

1/9 czy 1/3 to sa ulamki
