**bobpursley**, Friday, September 28, 2007 at 7:25pmwell, 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.

**Marty**, Friday, September 28, 2007 at 7:27pmDoes the answer have to be in scientific notation?

If so, how would you figure it out?

10^2 X 10^2=10^4

and you get...

Y X 10^4

**Jenn**, Friday, September 28, 2007 at 7:37pmThere 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)
