Question

8x10-3 is how many times as great as 4x10-6

Answer 1

8x10^-3 is 2000 times as great as 4x10^-6, which can be found by dividing the former by the latter and simplifying the result (8/4)x10^(3).

Step-by-step explanation:

To find out how many times greater 8×10-3 is than 4×10-6, we can divide the former by the latter. This is a simple comparison of two numbers in scientific notation. Here's how you do it step by step:

1. Write down the numbers: 8×10-3 and 4×10-6.
2. Divide the first number by the second number: (8×10-3) / (4×10-6).
3. Divide the coefficients (8/4) and subtract the exponents (-3 - (-6)):
4. Calculating the coefficients gives 2 and the exponents give 3 (since -3 - (-6) = 3).
5. Combine the result: 2×103.

Therefore, 8×10-3 is 2×103, or 2000 times as great as 4×10-6.
