100000000000000000000000000000000*1000000000000000000000000000

To multiply the two numbers \(10^{30}\) and \(10^{27}\):

\[ 100000000000000000000000000000000 \times 1000000000000000000000000000 = 10^{30} \times 10^{27} = 10^{57} \]

So, the result is:

\[ 1000000000000000000000000000000000000000000000000000000000000000 \]

or \(10^{57}\).
