Final answer:
No, it is not in scientific notation. The number 12 x 10^7 can be written in scientific notation as 1.2 x 10^8.
Step-by-step explanation:
No, it is not in scientific notation. In scientific notation, a number is written as the product of a decimal number and a power of 10. The decimal number must be greater than or equal to 1, but less than 10. In the given number, 12 is less than 10, but it is not written as a decimal number between 1 and 10. The number 12 x 10^7 can be written in scientific notation as 1.2 x 10^8.
