Answer 1

Explicație pas cu pas:

13¹⁴•3-13¹³•2-13¹² = 13¹²•(3•13² - 2•13 - 1) = 13¹²•(3•169 - 26 - 1) = 13¹²•(507 - 27) = 480•13¹²

Answer 2

Răspuns: $\red{\bf \underline{13^{12}\cdot480}}$

Explicație pas cu pas:

$\bf 13^{14}\cdot3-13^{13}\cdot2-13^{12}=$

$\bf 13^{12}\cdot\Big(13^{14-12}\cdot3-13^{13-12}\cdot2-13^{12-12}\Big)=$

$\bf 13^{12}\cdot\Big(13^{2}\cdot3-13^{1}\cdot2-13^{0}\Big)=$

$\bf 13^{12}\cdot\Big(169\cdot3-13\cdot2-1\Big)=$

$\bf 13^{12}\cdot\Big(507-26-1\Big)=$

$\red{\bf \underline{13^{12}\cdot480}}$
