#14.304 * 10^4#

Or

#1.4304 * 10^5#

First, we can rewrite this expression as:

#(3.00 * 4.768) * (10^-2 * 10^6) = 14.304(10^-2 * 10^6)#

We can now use this rule for exponents to multiply the 10s terms:

#x^color(red)(a) xx x^color(blue)(b) = x^(color(red)(a) + color(blue)(b))#

#14.304(10^color(red)(-2) * 10^color(blue)(6)) = 14.304 * 10^(color(red)(-2)+color(blue)(6)) = 14.304 * 10^4#

Or

#1.4304 * 10^5#
