    well, when muliplying, the answer is limited to the number of significant digits of the least precise number: In this case, the 2.7 dominates as the least precise.

    Does the answer have to be in scientific notation?
    If so, how would you figure it out?

  • Significant Digits -

    you do 2.7 X 4.23=Y
    10^2 X 10^2=10^4
    and you get...
    Y X 10^4

    Welcome

    There is also a way to do this in a graphic calculator...
    first put your calculator into degree and scientific mode
    Next type each problem in like this:
    (2.7,2) x (4.23,2) which will give you your answer. (*when u put the comma in, the calculator will show an E instead)
