To multiply 8.94 × 10⁹ by 10⁵ and divide the result by 3, we can first multiply the two numbers together, and then divide by 3:
8.94 × 10⁹ × 10⁵ / 3 = 8.94 × 10⁴ × 10⁹
To express this result in scientific notation, we can write 8.94 × 10⁴ as 8.94 × 10⁴ × 10⁰, and then combine the exponents of 10:
8.94 × 10⁴ × 10⁹ = 8.94 × 10¹³
Therefore, the answer in scientific notation is 8.94 × 10¹³.
