Explicație pas cu pas:
a. 1²⁰²⁰-2020⁰+3²-2³=
= 1 - 1 + 9 - 8 =
= 0 +1
= 1
b. 2¹²:2¹⁰+5²-3²+2018⁰=
= 2^2 + 25 - 9 + 1
= 2 + 25 - 9 + 1
= 27 - 9 +1
= 18 + 1
= 19
c.2019⁰+1²⁰¹⁹+2018¹+0²⁰¹⁸-2017¹=
= 1 +1 + 2018 + 0 - 2017
= 2 + 2018 - 2017
= 2 + 1
= 3
d.[(2³+2⁴+2⁵+2⁶)+(2²+2³)]×(1+3+3²+3³) =
= [( 8 + 16 + 32 + 64) + (4+8)] × ( 4 + 9 + 27)
= [ ( 40 + 80) + 12] × ( 13 + 27)
= (120 + 12) × 40
= 132 × 40
= 5280

a) 1²⁰²⁰-2020⁰+3²-2³=1-1+9-8=0+9-8=9-8=1
b) 2¹²:2¹⁰+5²-3²+2018⁰=2^(12-10)+25-9+1=2²+25-9+1=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)]×(4+9+27) = [(24+32+64)+12]×(13+27) = [(56+64)+12]×50=(120+12)×40=132×40=5280
