A 3.0 x
B 3.0 x
C 3.0 x
D 3.0 x
E 3.0 x

Answer 1

I don't have the full expressions — the problem statement you pasted looks incomplete. Could you paste the two numbers being divided (or the complete multiple-choice options)?

Meanwhile, here's the general method and a quick example so you can finish it yourself:

Method for dividing numbers in scientific notation
1. Divide the coefficients (the decimal parts).
2. Subtract the exponents: 10^(a) / 10^(b) = 10^(a−b).
3. Combine: (coeff quotient) × 10^(exponent difference).
4. If the coefficient is not between 1 and 10, adjust by moving a power of 10 and change the exponent accordingly so the result is in proper scientific notation.

Example
(3.0 × 10^8) ÷ (3.0 × 10^2)
= (3.0 ÷ 3.0) × 10^(8−2)
= 1 × 10^6
= 1.0 × 10^6 (scientific notation)

Give me the two full numbers (or the full multiple-choice options) and I’ll compute the exact answer.
