Question

Dau 50 de puncte + coroana​

Answer 1

Explicație pas cu pas:

$= {(4 - 3)}^{100} + 5 \div [9 - 4 \cdot (3 - 1)] \cdot 1 =$

$= {1}^{100} + 5 \div (9 - 4\cdot 2) = 1 + 5 \div (9 - 8) =$

$= 1 + 5 \div 1 = 1 + 5 = 6$

--

$= 441 - 2\cdot [121 + 21 : 1 + 2 \cdot (1 + 8\cdot3 + 16 - 2)] =$

$= 441 - 2\cdot [121 + 21 + 2 \cdot (1 + 24 + 14)] =$

$= 441 - 2\cdot (142 + 2 \cdot 39) = 441 - 2\cdot (142 + 78) =$

$= 441 - 2\cdot 220 = 441 - 440 = 1$

Answer 2

Răspuns:

6 , 1

Explicație pas cu pas:

(2²-3)¹⁰⁰+5:[3²-4×(3¹-3⁰)]×1²⁰¹³=

=(4-3)¹⁰⁰+5:[9-4×(3-1)]×1=

=1¹⁰⁰+5:(9-4×2)×1=

=1+5:(9-8)×1=

=1+5:1×1=

=1+5×1=

=1+5=

=6

21²-2×{11²+21:(2-1)+2×[1+2³×(1+2)+2⁴-2¹]}=

=441-2×[121+21:1+2×(1+8×3+16-2)]=

=441-2×[121+21+2×(1+24+16-2)]=

=441-2×[121+21+2×(41-2)]=

=441-2×(121+21+2×39)=

=441-2×(142+78)=

=441-2×220=

=441-440=

=1
