401,000,000 in scientific notation

4.01*10^8

To write 401,000,000 in scientific notation, follow these steps:

1. Move the decimal point in the original number so that only one non-zero digit is to the left of the decimal point. In this case, you would move the decimal point 8 places to the left, resulting in 4.01.

2. Count the number of places you moved the decimal point. In this case, since you moved it 8 places to the left, the exponent will be positive 8.

3. Rewrite the number in scientific notation by expressing it as the product of the non-zero digit and the power of 10. In this case, it would be 4.01 x 10^8.

Therefore, 401,000,000 in scientific notation is 4.01 x 10^8.
