Пошаговое объяснение:

Answer 2

a) To solve the expression 231 + 112 - 223 - 109, we can perform the operations in the given order:

231 + 112 = 343 343 - 223 = 120 120 - 109 = 11

Therefore, the value of the expression is 11.

b) To solve the expression 322 : 23 · 22 - 483.9 : 23, we need to follow the order of operations (PEMDAS/BODMAS):

322 : 23 = 14 14 · 22 = 308 483.9 : 23 ≈ 21.043

Now we can substitute these values into the expression:

308 - 21.043 ≈ 286.957

Therefore, the value of the expression is approximately 286.957.

e) To solve the expression (24 * 7 - 676 : 13) * 13 - 238, we again follow the order of operations:

24 * 7 = 168 676 : 13 = 52 168 - 52 = 116 116 * 13 = 1508 1508 - 238 = 1270

Therefore, the value of the expression is 1270.
