See a solution process below:

First, rewrite this expression as:

#(3 xx 2)(10^-12 xx 10^10) => 6(10^-12 xx 10^10)#

Now, use this rule of exponents to multiply the 10 terms:

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

#6(10^color(red)(-12) xx 10^color(blue)(10)) => 6 xx 10^(color(red)(-12) + color(blue)(10)) => 6 xx 10^-2#

Or, converting out of scientific terms:

#0.06#
