Answer:

#47,000=4.7*10^4#

Explanation:

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#
