Question

8 x 10^-3 is how many times as great as 4 x 10^-6

Answer 1

For this case we can rewrite the expressions as:

$3 * 10 ^ {- 3} = 0.003$

That is, we run the decimal three times to the left.

$4 * 10 ^ {- 6} = 0.000004$

That is, we run the decimal six times to the left.

So:

$0.003-0.000004 = 0.002996$

So, we have that $3 * 10 ^ {- 3}$is 0.002996 times bigger than $4 * 10 ^ {- 6}$

Answer:

$3 * 10 ^ {- 3}$is 0.002996 times bigger than $4 * 10 ^ {- 6}$

Answer 2

Answer: The first number is 2000 times greater than second number.

Step-by-step explanation:

Let the first number be 'x' and second number be 'y'

We are given:

x = $8\times 10^{-3}$

y = $4\times 10^{-6}$

To calculate the times, number 'x' is greater than number 'y', we divide the two numbers:

$\frac{x}{y}=\frac{8\times 10^{-3}}{4\times 10^{-6}}\\\\\frac{x}{y}=2\times 10^3\\\\x=2000y$

Hence, the first number is 2000 times greater than second number.
