#8.19*10^-2#

Explanation:

#(9.75 * 10^3)*(8.4 * 10^-6)#

First, let's regroup the factors,

#=> (9.75 * 8.4)(10^3*10^-6)#

We can now proceed with multiplication

#=> (81.9)*(10^-3)#

Now let's transform this to scientific notation.

#=> (8.19 * 10)(10^-3)#

#=> 8.19*(10*10^-3)#

#=> 8.19*(10^1*10^-3)#

#=> 8.19*(10^-2)#
