234^789 = 10^x

789 log 234 = x log 10 = x

789 * 2.37 = x

x = 10^1869

let x = 234^789

log x = log 234^789

= 789 log 234 = 1869

then x = 10^1869

so 234^789 = 1.0 x 10^1869

or really

x = 10^1869.311311....

.311311311311..... is a ratio of rational numbers which you could figure out if you choose, but that is probably beyond what the problem asks for.
