Sure! To write the expression [tex]\(9 \times 10^4\)[/tex] as an ordinary number, follow these steps:
1. First, understand that [tex]\(10^4\)[/tex] means multiplying 1 by 10 four times, which is equivalent to 10,000.
2. Next, multiply 9 by 10,000:
[tex]\[
9 \times 10,000 = 90,000
\][/tex]
Therefore, the expression [tex]\(9 \times 10^4\)[/tex] written as an ordinary number is [tex]\(90,000\)[/tex].
