d}(1,1)[2]+(-1,1)[2]=
e}(1,1)[4]-(-1,1)[2]

Answer 1

A)
(-3)×(-3)×(-3)×(-3)+(-4)×(-4)×(-4)=
=81+64=145
b)
(-15,5)×(-15,5)+(-10,5)×(-10,5)+(5,5)×(5,5)=
=240,25+110,25+30,25=380,75
c)
1+(2/7)+(2/7×2/7)+(2/7×2/7×2/7)=
=1+(2/7)+(4/49)+(8/343)=1+18/49+(8/343)=
=1+126/343+8/343=1i134/343
d)
(1,1)×(1,1)+(-1,1)×(-1,1)=1,21+1,21=2,42
e)
(1,1)×(1,1)×(1,1)×(1,1)-(-1,1)×(-1,1)=
=1,4641-1,21=0,2541
