Write \( 7 \times 10^{4} \) as an ordinary number.

To convert \( 7 \times 10^{4} \) into an ordinary number, you simply move the decimal point in the number 7 four places to the right. This gives you 70,000. So, \( 7 \times 10^{4} \) is equal to 70,000. If you ever forget how to convert scientific notation, just remember that the exponent tells you how many places to move the decimal. A positive exponent means you’re moving to the right, which can turn small numbers into big ones! This handy trick can come in useful in everything from science classes to daily life scenarios like calculating distances in miles or amounts in a bank account!
