scientific notation only has 3 significant digits
so how do you find the answer
It can have as many significant figures as you like.
generally written in 3 sig digits of course you can have as many as you like...
There's no generally about it, it depends on the number.
you want it in the form #.####*10^x with however many #'s are appropriate, but always one to the left of the decimal. Then you look at how many digits you have to move that decimal to get to the actual number you're converting to scientific notation. In this case you move the decimal two spots to the right so x=2 1.6252*10^2 of you are moving the decimal to the left x is negative
if you are*
so are you saying the answer is 1.6252*10^2
what about of the question 0.0001 would it 0.1x10^-3
usually we write 1.0 x10^-4 but your answer is right too.
and yeah 1.6252x10^2 is right
