○ a 8.0619 × 10⁵
○ b 8.0619 × 10²⁴
○ c 8.0619 × 10¹⁰
○ d 8.0619 × 10⁻²

Explanation:

Step1: Rearrange terms (commutative property)

$(2.31 \times 3.49) \times (10^4 \times 10^6)$

Step2: Multiply the decimal values

$2.31 \times 3.49 = 8.0619$

Step3: Multiply the powers of 10

$10^4 \times 10^6 = 10^{4+6} = 10^{10}$

Step4: Combine the results

$8.0619 \times 10^{10}$

Answer:

c. $8.0619 \times 10^{10}$
