Divide. Write your answer in scientific notation. 4 × 10⁻⁵ 8 × 10⁻¹³

To divide the two numbers in scientific notation, you can follow these steps:

1. Divide the coefficients: ( frac{4}{8} = 0.5 )
2. Subtract the exponents: ( -5 – (-13) = -5 + 13 = 8 )

Now, you combine these results into scientific notation:

[ 0.5 times 10^8 ]

The correct answer is:

A) 0.5 × 10⁸ (Note that B also states the same but is listed twice).
