To find out how much money Gina receives on Thursday, let's break down the amounts she receives each day of the week starting from Monday:

- On **Monday**, she receives \(2\) dollars. This can be represented as \(2^1\).
- On **Tuesday**, she doubles the amount she received on Monday, thus she receives \(2 \times 2 = 4\) dollars, which is \(2^2\).
- On **Wednesday**, she doubles the Tuesday amount to get \(2 \times 4 = 8\) dollars, which is \(2^3\).
- On **Thursday**, she doubles the Wednesday amount to get \(2 \times 8 = 16\) dollars, which is \(2^4\).

Now, let's summarize the amounts:

- Monday: \(2^1\)
- Tuesday: \(2^2\)
- Wednesday: \(2^3\)
- Thursday: \(2^4\)

Thus, the amount Gina receives on **Thursday** is represented by \(2^4\).

Therefore, the answer is **\(2^4\)**.
