It is: 6.0*10^-6 in scientific notation
In general, you cannot. If the number in scientific notation has not been rounded then express it is normal form and proceed from there.
Sometimes. Scientific notation is used to express very small or very large numbers. If the problem does not involve any such numbers then there is no need for scientific notation.
It would depend on what calculation you are solving.

Scientific notation is not a puzzle or equation that needs to be "solved". You do not "solve" rational fractions - they are just a way of representing numbers. In the same way, scientific notation is simply one way of representing numbers. It is usually used for very large or very small quantities.
7.19 × 10-4 or 7.19E-4
Multiplying each factor by powers of ten
It would depend on what calculation you are solving.
There is no single solution to all questions involving scientific notation. Different questions have different answers and so the question will need to be more specific.
It is 8.9*10^-5 in scientific notation
111111111111 x 111111111111 is a math problem. To solve this, you have to put it in scientific notation.
