An example of a number in scientific notation would be 3.7 x 10⁶
You can apply scientific notation to any number. However, it usually makes sense to do so if the number is greater than at least one million or smaller than a millionth.
Well there is many scientific names but you have to make sure that it make sense
8421032.9266 = 8.4210329266 × 10⁶ Scientific notation is generally used for very large and small numbers, so you would not normally have so many decimal places and would round to a number of significant figures.
They do that because they want their writing to stand out and make sense
It is 1.79875475*107, although it would make sense to reduce the number of figures in the mantissa: for example to 1.80*107.
makes no sense..do you mean 95%
Mercury's mass is 0.055 times the mass of the Earth. In kilograms, Mercury has 3.3022×1023 kg. Writing this in "standard form" - I assume you mean, not in scientific notation - really doesn't make sense for such large numbers. But you can do it if you like - just move the decimal point 23 digits to the right, and fill out missing digits with zeros.
When it is a very large number for example 100,000,000,000 = 1.0*1011 Or when it's a small number like 0.00000000001=1*10-11
Olfaction.
The fractional notation for 1 is 1, or it could also be any whole number atop itself (i.e. 1/1, 2/2, 257/257, 716948355/716948355)... Did you mean 'What is fractional notation for 1%?'? That seems to make more sense to me: 1% (or one per hundred), is 1/100.
Yes a scientific theory has to make sense. If it did not, scientists would not have enough information to understand and continue to gather data on the theory.
