The answer 5.294*10^(-23) from the other tutor has 4 significant digits, not 3.

The number of decimal places is not the same thing as the number of significant figures.

In particular, in scientific notation, there is always 1 significant figure to the left of the decimal point; so a number in scientific notation with n significant figures will have (n-1) digits after the decimal point.

ANSWER: (1/2)^74 written in scientific notation with 3 significant figures is 5.29*10^(-23)
