Explanation:

Step1: Multiply units digit

Multiply 0 (units digit of 610) by 9: \(0\times9 = 0\). Units place of result is 0.

Step2: Multiply tens digit

Multiply 1 (tens digit of 610) by 9: \(1\times9 = 9\). Tens place of result is 9.

Step3: Multiply hundreds digit

Multiply 6 (hundreds digit of 610) by 9: \(6\times9 = 54\). Write 4 in hundreds place and carry over 5.

Step4: Add carry over

There's a carry over of 5, so thousands place is 5.
Combining, the result is 5490.

Answer:

5, 4, 9, 0 (the four digits in order from thousands to units place)
