) − (3 ×
).

C 1.7 ×
D 1.7 ×

Answer 1

I can't read the full expression — some numbers/superscripts are missing from your post. Could you repost the problem exactly (or upload a picture)?

Meanwhile here are a few likely interpretations and their results so one may match what you meant:

- If the problem is (2×10^3) − (3×10^2):
2000 − 300 = 1700 = 1.7 × 10^3.

- More generally, if it is (2×10^n) − (3×10^(n−1)):
2·10^n − 0.3·10^n = 1.7·10^n.

- If the two factors are the same a, i.e. (2×a) − (3×a):
= −a.

If you paste the exact numbers (or the original image), I’ll give the precise choice and steps.
