Answer 1

In scientific notation, a number is represented by the product of a number whose absolute value is greater than or equal to 1 and less than 10 and an integer power of 10.

In general, it is \(a \times 10^n\)
An example is: \( 5.05 \times 10^{-5} \)

The number -909,060 has to use the number -9.0906 as the number whose absolute value is greater than or equal to 1 and less than 10.

Now you need to figure out which exponent to use on the 10.
What do you multiply -9.09060 to get -909,060?
