Why is 9.854 x 107.6 not a scientific notation?

Answer 1

Scientific notation is always written as a number (between 1 and 10) multiplied by a power of ten.

For example: 107.6 in scientific notation would be 1.076 x 102 notice how the first number is between 1 and 10 and it is being multiplied by a power of ten.

So the example you gave is not written in the same format and is thus not written in scientific notation.

If you were to write it in scientific notation you would multiply the two numbers and then convert the answer to scientific notation and write it as:

1.0602904 x 103
