Given:
(1.5*10^-14) * (3.8394*10^10) / (2.45)
How can I find the answer to this question and record it in exponential notation?
(to two sig figs)
Start by doing it as two separate problems: and . The first is "ordinary arithmetic" and for the second, as e^(i*pi) says, you add the exponents: [itex]10^{-14+ 10}[/itex].
If the result of [tex]\frac{(1.5)(3.8394)}{2.45}[/itex] is not between 1 and 10, change it also into "scientific notation" and add the exponent to what you got for the second expression. Don't forget to reduce to two signifcant figures.
