Answer 3

Let's break down the expression step by step:

First, let's simplify the expression within the first parentheses: 628 - 624 = 4

Now, let's simplify the expression within the second parentheses: 92 * 8 = 736 736 - 721 = 15

Now, let's substitute the simplified values back into the original expression:

213696:4*67 + 420:15

Next, let's perform the division operation:

213696 / 4 = 53424 420 / 15 = 28

Substituting the new values:

53424 * 67 + 28

Finally, let's perform the multiplication and addition:

53424 * 67 = 3,578,608 3,578,608 + 28 = 3,578,636

Therefore, the value of the expression 213696:(628-624)67+420:(92*8-721) is 3,578,636.
