D.6.23*10^3

Answer 1

I believe A is the answer

Answer 2

For this case, they ask us which of the given numbers, in scientific notation, is greater.

So:

$6.23 * 10 ^ {12} = 6,230,000,000,000$ is equivalent to rolling the decimal 12 times to the right.

$6.23 * 10 ^ 8 = 623,000,000$ is equivalent to rolling the decimal 8 times to the right.

$6.23 * 10 ^ {-6} = 000000623$ is equivalent to rolling the decimal 6 times to the left.

$6.23 * 10 ^ 3 = 6,230$ is equivalent to rolling the decimal 3 times to the right.

Thus, we observe that the greatest number is $6.23 * 10 ^ {12}$
