Pomóżcie mi w rozwiążaniu zadania 5 i 6 z maty dam naj. z gówy wiellkie dzięki
zad.5
a=(1/3)⁻¹*9⁻¹+(1/2)⁻¹*4⁻¹=3*1/9+2*1/4=1/3+1/2=2/6+3/6=5/6
b=6⁻³*(1/6)⁻³= 6⁻³*6³ =1:27/8=8/27
(2/3)⁻³ (3/2)³
b:a=8/27:5/6=8/27*6/5=18/45
zad.6
a=(3/4)⁻²:3⁻²=16/9*9=16
b=-(1 1/3)⁻²*(3/4)⁻²=-9/16*16/9=-1
a-b=16-(-1)=17
pozdrawiam
