Question

what is this number written in scientific notation? 3,400,000 = ? × 10^

Explanation:

Step1: Determine the coefficient

To write a number in scientific notation, we need a number between 1 and 10 (including 1, excluding 10) multiplied by a power of 10. For 3,400,000, we move the decimal point to the left until we get a number between 1 and 10. Moving the decimal point 6 places to the left from 3,400,000 gives us 3.4. So the coefficient is 3.4.

Step2: Determine the exponent

The number of places we moved the decimal point is the exponent of 10. Since we moved the decimal point 6 places to the left, the exponent is 6.

Answer:

$3.4\times10^{6}$
