$47,000=4.7*10^4$

When writing numbers in scientific notation, we want one non-zero digit in front of the decimal point.

In the number $47,000$ , the decimal is essentially at the end of the number:

$47,000.$

We can loop the decimal point $4$ times to the left to get:

$4.70$

Recall, we looped our decimal $4$ times, and to the left, so the power of $10$ will be a positive $4$ , thus:

$47,000=4.7*10^4$
