Final answer:
To express 4567000000000000000 in exponential form, it becomes 4.567 × 10 to the power of 18.
Step-by-step explanation:
To express the number 4567000000000000000 in exponential form, also known as scientific notation, we need to rewrite it as a product of a number between 1 and 10 and a power of 10.
First, place the decimal after the first non-zero digit. In this case, we place it after the 4, which gives us 4.567. We then count how many places we moved the decimal.
Here, the decimal moved 18 places to the left, since the original number was 4567000000000000000.
Therefore, the number in scientific notation is 4.567 × 1018.
