b. yes, the number is written in scientific notation ****
c. no, the first factor is not a number between 1 and 10

Scientific notation:

you are wrong on b.

To determine if a number is written in scientific notation, we need to check if it is written as a number multiplied by a power of 10.

In the given number, 4.8 x 100^7, we have the number 4.8 multiplied by 100 raised to the power of 7.

Since the number is written as a product of a number and a power of 10, it is in scientific notation. Therefore, the answer is b. yes, the number is written in scientific notation.
