Answer 1

I don't have the full calculator display — I only see "5.49". Could you confirm whether there is an exponent (for example "5.49E3" or "5.49×10^4") or upload a picture/screenshot?

If the display really is just 5.49 (no exponent), then:
- Scientific notation: 5.49 × 10^0
- Standard form: 5.49

If there is an exponent shown (e.g. 5.49E3), tell me the exponent and I will convert it to both scientific and standard form.
