Witaj:)
oblicz [4/5 +4.3(0,4-23)do potęgi 3 ostatni nawias] =
4/5 + 43/10 * 22,6³= 4/5 + 43/10 * (226/10)³=
4/5 + 11543176/10000=8000/10000+11543176/10000=
11551176/10000=1155,1176

Oblicz [4/5 +4,3(0,4-23)do potęgi 3 ostatni nawias]

[4/5 +4.3(0,4-23)³] =
=4/5 -43/10 * 22,6³=
= 4/5 - 43/10 * (226/10)³=
=0,8- 496356568/10000=
=0,8-49635,6568=-49634,8568

chyba ze chodzilo o to

[4/5 +4,3(0,4-23)]³ =
= [4/5 +4,3(-22,6)]³ =
= [0,8 -97,18]³ =
=[-96,38]³

Oblicz [4/5 +4.3(0,4-23)do potęgi 3 ostatni nawias]

[0.8 + 4.3(-22.6)] do 3
[ 0.8+(-97.18)] do 3
(-96.38) do 3
