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: 6.0*10^-6 in scientific notation
8
It is: 6.0*10^1
In general, you cannot. If the number in scientific notation has not been rounded then express it is normal form and proceed from there.
yes marks will be deducted if scientific notation is not followed as scientific notation has specific meaning .thus it is better to use scientific convention
228.1 = 2.281 x 102
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.
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.
What you would do on this questions is you would move the decimal to the right and o.ooooooo875 in scientific notation should be 8.75 × 10-8
