The answer is $1.6xx10^11$ .

Multiply the coefficients.

$1.6xx9.9=15.84=16$ (due to significant figures)

Add the exponents on the base 10.

$10^4*10^6=10^(4+6)=10^10$

Put them together.

$16xx10^10$

Now convert the answer back into scientific notation.

Move the decimal to the left one place, and increase the exponent by one.

$1.6xx10^11$
