how can you show 198,000 as a power of 10 using an exponent?

Answer 1

Rounded it would be, 2x10^5

Not rounded it would be, 198x10^3

Answer 2

To show 198,000 as a power of 10 using an exponent, we need to express it in scientific notation. 198,000 can be written as 1.98 x 10^5. In this representation, the decimal point is moved 5 places to the left to make the number between 1 and 10, and the exponent indicates how many places the decimal point was moved.
