68000:17+640:160

To solve the expression \( 68000:17 + 640:160 \), we first perform each division separately.

1. Calculate \( 68000:17 \): \[ 68000 \div 17 = 4000 \]

2. Calculate \( 640:160 \): \[ 640 \div 160 = 4 \]

Now, we add the results of the two calculations: \[ 4000 + 4 = 4004 \]

Thus, the final answer is: \[ \boxed{4004} \]
