x=8³³:[4³²·2³⁴+(2⁵·2²⁰)⁵:(16·2²³)+(7⁵:7⁵-1)³²·4]=2⁹⁹:[2⁶⁴·2³⁴+(2²⁵)⁵:(2⁴·2²³)+(1-1)³²·4]=2⁹⁹:(2⁹⁸+2¹²⁵:2²⁷+0·4)=2⁹⁹:(2⁹⁸+2⁹⁸)=2⁹⁹:2·2⁹⁸=2⁹⁹:2⁹⁹=1
y=[(11-0¹¹)·(3³-3²)+1²⁰²⁰]·(3²-2³)-3²·2=[11(27-9)+1]·(9-8)-9·2=(11·18+1)·1-18=198-18=180
(x la puterea y) +yˣ=1¹⁸⁰+180¹=1+180=181
4) a) (2+2·3){2·2²·2⁴³-2⁴⁶+[3¹⁴⁸:3⁴³-(3⁵)²¹]+16}=8·[2⁴⁶-2⁴⁶+(3¹⁰⁵-3¹⁰⁵)+16]=
=8·(0+0+16)=8·16=128
b) 122+12·{183:[(2·3²·5³)⁴:(2⁴·3⁷·5¹²)+(2⁸)⁹:2⁷²-1²⁷·5⁰]-9·(54-2⁴·3)}=
=122+12·{183:[(2⁴·3⁸·5¹²):(2⁴·3⁷·5¹²)+2⁷²:2⁷²-1·1]-9·(54-16·3)}=
=122+12·[183:(3+1-1)-9·(54-48)]=122+12·(183:3-9·6)=122+12·(61-54)=
=122+12·7=122+84=206
