Va rog cat mai repede

Answer 1

Explicație pas cu pas:

[(2²)³-1995⁰]:3²¹-(1²³+4¹²)=?

(2^6 - 1) : 3^21 - 1 - 4^12=

(64-1) : 3^21 - 1 - 4^12 =

63 : 3^21 - 1 - 4^12 =

$\frac{7 \times 9}{ {3}^{21} } - 1 - {4}^{12} = \\ \frac{7 \times {3}^{2} }{ {3}^{21} } - 1 - {4}^{12} = \\ \frac{7}{ {3}^{19} } - 1 - {4}^{12}$
