x+2⁰*(2¹⁹⁹⁰*2+2¹⁹⁹¹+2¹⁹⁹²)=2¹⁹⁹⁴
x+1*[2¹⁹⁹⁰(2+2+2²)]=2¹⁹⁹⁴
x+2¹⁹⁹⁰*2³= 2¹⁹⁹⁴
x=
x=2¹⁹⁹⁴-2¹⁹⁹³
x= 2¹⁹⁹³ *(2-1)
x= 2¹⁹⁹³
2. O fântână arteziană in forma unui paralelipiped dreptunghic are
dimensiunile: 20,1 dm; 234 cm; 0,12 dam. Calculati cu cati litri de apa
234 cm= 23,4 dm
0,12dam= 12dm
V= 12*23,4*20,1=5644, 08 dm³= 5644,08 l
