A. 9,300
B. 93,000
C. 930,000
D. 9,300,000



Answer :

To convert a number written in scientific notation to standard notation, you need to multiply the base number by 10 raised to the given power. Here, the base number is 9.3 and the exponent is 5.

When multiplying by \(10^5\), you are essentially moving the decimal point 5 places to the right.

Starting with the number 9.3, let’s move the decimal point 5 places to the right:
1. 93
2. 930
3. 9300
4. 93000
5. 930000

So, by moving the decimal point 5 places to the right, 9.3 becomes 930000.

Therefore, the correct standard notation for \(9.3 \times 10^5\) is \(930,000\).

Thus, the correct answer is:

C. 930,000
