Question

Which list is in order from least to greatest?

Answer 1

For this case what you must remember is that in the scientific notation we have two cases:

1) If the exponent is negative, the decimals move to the left

2) If the exponent is positive, the decimals are turned to the right.

We have then the following numbers:

$1.25 * 10 ^ {-2} = 0.0125\\8.1 * 10 ^ 4 = 81000\\6 * 10 ^ 4 = 60000\\1.94 * 10 ^ {-5} = 0.0000194$

Answer:

in order from least to greatest we have:

$1.94 * 10 ^ {-5} = 0.0000194\\1.25 * 10 ^ {-2} = 0.0125\\6 * 10 ^ 4 = 60000\\8.1 * 10 ^ 4 = 81000$

Answer 2

They would be 1.94, 1.25, 6, 8.1!

Hope it help!
