Answer:  3 \times 10^{13}

Explanation:

Highlight the first digit on the very left (2). The 7 right next to it means we'll round that 2 up to a 3. Every other digit becomes a zero.

It converts to the scientific notation 3 \times 10^{13} because we basically start with 3.0 and move the decimal point 13 spots to the right to arrive at 30 trillion as shown above.
