To find this, you have to solve 103(2^t)
Since there are 103 bacteria to begin with, you multiply this by how often the bacteria divides (every two hours) to the power of how many times they have divided in that time, or t. The bacteria has divided 3 times in 6 hours.

The final answer is 824 bacteria
