Answer 1

When you have a small number and you are making it bigger, the exponent will be a negative number. You'll need to move the decimal point between the first two numbers after the 0's so in this case, the decimal point will go between the 9 and the 5.

The final answer after rounding will be $9.54$ × $10^{-3}$.
