Answer 1

I can’t see the calculator display — could you type what it shows (for example “1.2E-10” or “1.2×10^−10”) or upload the image?

Meanwhile, here’s how to convert the common “E”/scientific forms to the answer choices:
- 1.2E-10 = 0.00000000012 → choice A
- 1.2E12 = 1,200,000,000,000 → choice B
- 1.2E-12 = 0.0000000000012 → choice C
- 1.2E10 = 12,000,000,000 → choice D

Tell me the exact display and I’ll pick the correct choice.
