Answer 1

To convert the number 28,500,000 to scientific notation:

1. Move the decimal point to create the coefficient: 2.8500000.
2. You move the decimal point 7 places to the left to get from 28,500,000 to 2.85.

Thus, you write it in scientific notation as:
\[ 2.85 \times 10^7 \]

So, the value of \( x \) in the scientific notation \( 2.85 \times 10^x \) is:
x = 7.
