Answer 1

I think part of the options got cut off — the exponent (the "×10^…") is missing. Can you repost the full choices or an image of the problem?

Meanwhile, here’s how to decide once you have the full scientific notation:

- If the numbers are written as a × 10^n, first compare the exponents n. The number with the smallest exponent is the smallest (because a fixed coefficient times a smaller power of 10 gives a smaller value).
- If two numbers have the same exponent, compare their coefficients (the a values): the smaller coefficient gives the smaller number.
- If you prefer, convert each to standard decimal form and compare.

Example: Which is smallest: 1.28×10^3, 2.85×10^2, 3.24×10^4?
- Exponents: 3, 2, 4 → 2 is smallest, so 2.85×10^2 is the smallest (285).

Send the full options and I’ll pick the correct one.
