To convert a number from scientific notation to standard form, you need to multiply the base number by 10 raised to the given exponent.
In this case, we have [tex]\(6.9 \times 10^7\)[/tex], which means we take 6.9 and move the decimal point 7 places to the right, because the exponent is positive.
Starting with 6.9:
- Moving the decimal one place to the right gives us 69.
- Moving the decimal two places to the right gives us 690.
- Moving the decimal three places to the right gives us 6900.
- Moving the decimal four places to the right gives us 69000.
- Moving the decimal five places to the right gives us 690000.
- Moving the decimal six places to the right gives us 6900000.
- Moving the decimal seven places to the right gives us 69000000.
Therefore, [tex]\(6.9 \times 10^7\)[/tex] written in standard form is:
[tex]$69,000,000$[/tex]
The correct answer is [tex]\( \boxed{69,000,000} \)[/tex].
