To convert the number [tex]\(6.9 \times 10^7\)[/tex] to standard form, follow these steps:
1. Identify the base number and the exponent: The base number is [tex]\(6.9\)[/tex] and the exponent is [tex]\(7\)[/tex] in [tex]\(10^7\)[/tex].
2. The exponent [tex]\(7\)[/tex] tells us how many places to move the decimal point to the right.
3. Starting with [tex]\(6.9\)[/tex], move the decimal point 7 places to the right:
- Move once: [tex]\(69.\)[/tex]
- Move twice: [tex]\(690.\)[/tex]
- Move three times: [tex]\(6900.\)[/tex]
- Move four times: [tex]\(69000.\)[/tex]
- Move five times: [tex]\(690000.\)[/tex]
- Move six times: [tex]\(6900000.\)[/tex]
- Move seven times: [tex]\(69000000.\)[/tex]
So, [tex]\(6.9 \times 10^7\)[/tex] in standard form is [tex]\(69,000,000\)[/tex].
The correct answer is: [tex]\(69,000,000\)[/tex].
