Question

Express 3.46 x 10^6 as a normal number.

a) 3,460,000
b) 346,000
c) 34,600,000
d) 346

Answer 1

The number 3.46 x 10^6 expressed as a normal number is 3,460,000. This is done by moving the decimal point 6 places to the right due to the exponent on 10.

Step-by-step explanation:

To express 3.46 x 10^6 as a normal number, you move the decimal point 6 places to the right (because of the exponent of 10). Starting with 3.46, moving the decimal 6 places to the right gives us 3,460,000. Therefore, the correct representation of 3.46 x 10^6 in normal notation is 3,460,000, which corresponds to option a).

Let's take additional examples for practice:

• Expressing 6.022 × 10^23 in standard notation, you move the decimal 23 places to the right which gives us 602,200,000,000,000,000,000,000.
• For expressing '-890,000' in scientific notation, since the number is negative, we maintain the negative sign and express it as -8.9 × 10^5.
