What is 3 x 10^4 written as an ordinary number?
Answer and explanation
Correct answer: C. 30,000
- Step 1: 10^4 is 1 followed by 4 zeros. Step 2. 3 x 10,000 = 30,000. Answer: 30,000. Why not the others: 3,000: this moves the decimal one place too few. 300,000: this moves the decimal one place too many. 12: this multiplies the numbers instead of using the power of ten.
