$8.19*10^-2$

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

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.

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

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

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

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

What is (9.75 * 10^3) * (8.4 * 10^-6)(9.75 * 10^3) * (8.4 * 10^-6)?
