Final answer:
The number 3.5 x 10^7 is written in scientific notation. Therefore, the given statement is True.
Step-by-step explanation:
The number 3.5 x 107 is written in scientific notation.
In scientific notation, a number is represented as a product of a decimal number and a power of 10. The decimal number should be between 1 and 10, inclusive, and the power of 10 indicates the magnitude of the number.
In this case, the decimal number is 3.5, which is indeed between 1 and 10. The power of 10 is 7, indicating that the number is multiplied by 10 raised to the power of 7.
Therefore, the answer is True.
