Se considera nr rat u= 1,2 Si v= un întreg si 1 pe 3. Calculati :
a) u -1 ; b) u-v ; c) u:v ; d) v la a treia

Answer 1

u=1,2=12/10=6/5

v=1si 1/3 se introduce intregii in fractie=[(1×3)+1]/3=4/3

a) u-1=6/5-1=(6-5)/5=1/5

b) u-v     6/5-4/3=(3×6-4×5)/(5×3)=(18-20)/15=-2/15

d) v³    ( 4/3)³=4³/3³=64/27
