One terabecquerels, or 1000000000000 becquerel - depending on what you mean by "long hand".

You can write "equals". It would be perfectly fine to say "2 + 2 equals 4". It's jsut that, it's much more common to use "=", just because it's easier probably.
The second version (mN) would likely be confused with milli-newton.
-4
Probably 0.198% Thats how I would do it.
1.7 because 100 % equals 1 it would always be over 1
Expressed with the equals sign at the end, this sum would be written: 8 - (3 + 2.8) = 2.2
159x - 297 = 386.7
it equals to 8.10
e=mc^2? e/c^2 = m
How do you write 4x plus 4y equals 40 or how do you solve it? You would write it 4x+4y=40 you would solve it for y by subtracting 4x from both sides 4y=40-4x then divide all of that by 4y=40-4x/4 that's if you were graphing i have no idea what you're asking hope that helps if it's not too late.
To write 0.987 as a percentage, multiply it by 100 which equals 98.7%
