Regroup the coefficients and the exponents together and multiply separately
$3.045 * 10^5 * 6.853 * 10^6$
$= (3.045 xx 6.853) * (10^5*10^6)$

$3.045 xx 6.853 = 20.86738$
solve this by hand or use a calculator/spreadsheet

$10^5*10^6 = 10^(11)$
since $b^p xx b^q = b^(p+q)$

So
$3.045 * 10^5 * 6.853 * 10^6$
$= 20.86738 * 10^11$

or (if normalized)
$= 2.086738 * 10^12$
