Salutare!:)

a)

1²⁰²⁰-2020⁰+3²-2³=

1-1+9-8=

0+9-8=

9-8=

1

b)

2¹²:2¹⁰+5²-3²+2018⁰=

2²:5²-3²+2018⁰=

4+25-9+1=

29-9+1=

20+1=

21

c)

2019⁰+1²⁰¹⁹+2018¹+0²⁰¹⁸-2017¹=

1+1+2018+0-2017=

2+2018+0-2017=

2020+0-2017=

2020-2017=

3

d)

[(2³+2⁴+2⁵+2⁶):(2²+2³)]×(1+3+3²+3³)=

[(8+16+32+64):(4+8)]×(1+3+9+27)=

[(24+32+64):12]×(4+9+27)=

[(56+64):12]×(13+27)=

(120:12)×40=

10×40==
