Answer
To convert from scientific to decimal notation, look at the exponent of the base 10 power given (e.g. $3$ in $4.25677 \times 10^{3}$).
Move the decimal point to the right that many places. If we move the decimal point three places to the right in the example above, we will get $4256.77$.
Work Step by Step
2nd example: $9.147781 \times 10^{5}$
Because the exponent in the term with the base 10 is $5$, we know we're going to be moving the decimal point to the right FIVE places.
Doing so will give us $914778.1$, which is in decimal notation.
