Final answer:
The numbers 6.1×107 and 6.1×102 are already correctly expressed in scientific notation, where 6.1 is the coefficient and 107 and 102 represent powers of 10.
Step-by-step explanation:
The numbers 6.1×107 and 6.1×102 are already expressed in scientific notation. Scientific notation is a way of writing numbers that are too large or too small to be conveniently written in decimal form. It is commonly used by scientists, mathematicians, and engineers. In scientific notation, a number is written as the product of two factors: a decimal number that is at least 1 but less than 10, and a power of 10. For example, to express the number 610 in scientific notation, we would write it as 6.1×102, where 6.1 is the decimal number and 102 indicates that we move the decimal two places to the right. To clarify, the number 6.1×107 is already in the correct form for scientific notation, where '6.1' is the coefficient and '107' represents 10 raised to the seventh power. Similarly, 6.1×102 is also correctly written in scientific notation with '6.1' as the coefficient and '102' as 10 squared, or 100.
