Answer 1

(5692+2608)*20-62883=166000-62883=103117

Answer 2

To solve this expression, we need to first simplify the terms inside the parentheses by performing the addition operation:

39844:7 + 20864:8 = 5708 + 2608 = 8316

So the expression now becomes:

(8316 * 20) - (6987 * 9)

Multiplying 8316 by 20 gives us:

166320

Multiplying 6987 by 9 gives us:

62883

Subtracting 62883 from 166320 gives us:

103437

Therefore, the value of the expression (39844:7+20864:8) 20-69879 is 103437.
