scientific notation is always 10 to some power.

the decimal should be inbetween the first and second number, not counting zeros.

the first one: 0.00090674

should be: 00009.0674

you moved the decimal 4 places to the right.

this means that it is positive.

your answer would be 10^4 (to the fourth power)

same for the second one.

you have: 790640000.

should be: 7.90640000

you moved the decimal 8 places to the LEFT this time.

your answer would be 10^-8 (to the negative eighth power)

because you moved to the left, its negative.
