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}

Answer:

1.32 * 10 ^ 5
