Answer:

#color(green)("Another way of thinking about it!")#

Explanation:

Keep the decimal point stationary but slide the number until you end up with #5*43621#

This is not the same value we started with so we need to convert back. We do this by multiply it by #10xx10 =10^2#

#color(green)("(we moved the number 2 places, hence " 10^2)")"#

So #5*43621 xx 10^2 = 543*621#

Thus writing #543*621# in Scientific Notation gives #5*43621xx10^2#
