For this case we must indicate the value of the following expression, expressed in scientific notation:

(1.2 * 10^(-3)) * (1.1 * 10^(8)) =

We have that for multiplication properties of powers of the same base, the same base is placed and the exponents are added:

$a ^ n * a ^ m = a ^ {n + m}$

Then, rewriting the expression we have:

$(1.2 * 1.1) * 10 ^(- 3 + 8) =\\1.32 * 10 ^ 5$
