Answer 1

• 245+193-256 =

= (245-256)+193 = -11 + 193 = 182

• 25³-23³=

= (25-23) * (25² +25*23 + 23²)=

= 2 * (625 + 575 + 529)=

= 2 * (1200 + 529) = 2 * 1729 =

= 3458

• √256 -3²=

= √(16*16) - 3*3 = 16 - 9 = 7

Answer 2

Пошаговое объяснение:

$245 + 193 - 256 = 438 - 256 = 182 \\ {25}^{3} - {23}^{3} = 15625 - 12167 = 3458 \\\sqrt{256} -3^{2} = 16 - 9 = 7$
