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:
[tex] 1.25 * 10 ^ {-2} = 0.0125
8.1 * 10 ^ 4 = 81000
6 * 10 ^ 4 = 60000
1.94 * 10 ^ {-5} = 0.0000194
[/tex]
Answer:
in order from least to greatest we have:
[tex] 1.94 * 10 ^ {-5} = 0.0000194
1.25 * 10 ^ {-2} = 0.0125
6 * 10 ^ 4 = 60000
8.1 * 10 ^ 4 = 81000 [/tex]
