Answer 1

I can’t see the calculator display you mentioned. Tell me the value it showed (for example “7.64E16” or “7.64×10^-16”) and I’ll convert it.

Common conversions for the choices you gave:
- 7.64 × 10^16 = 76,400,000,000,000,000 (choice A)
- 7.64 × 10^21 = 7,640,000,000,000,000,000,000 (choice B)
- 7.64 × 10^-16 = 0.000000000000000764 (choice C)
- 7.64 × 10^-18 = 0.00000000000000000764 (choice D)

Tell me which scientific-notation display your calculator showed and I’ll confirm the correct choice.
