What is the result of (480 x 10 to the power of -5) divided by (60 x 10 to the power of -3)?

Explanation:
To solve the problem of dividing (480 x 10 to the power of -5) by (60 x 10 to the power of -3), we can break it down step by step. First, restructure the division of the two quantities: (480 x 10^(-5)) / (60 x 10^(-3)) can be rewritten as (480 / 60) x (10^(-5) / 10^(-3)). Now, calculate the first part, which is 480 divided by 60: 480 / 60 = 8. Next, we handle the exponent portion: 10^(-5) / 10^(-3) involves subtracting the exponents. When dividing like bases, you subtract the exponent of the denominator from the exponent of the numerator: -5 - (-3) = -5 + 3 = -2. Now, combine both results: 8 x 10^(-2). This means that the final answer is 8 x 10 to the power of -2. The scientific notation correctly represents numbers, and this result adheres to the rules for arithmetic with powers of ten. So, in this case, the correct answer aligns with option B
