sqrt(2)^1000 = sqrt(2)^(2xx500) = (sqrt(2)^2)^500 = 2^500

An approximate value for this would be 10^150 since 2^10 = 1024 ~= 1000 = 10^3

For a little more accuracy, use log_10 2 ~= 0.30103

then log_10 (2^500) = 500 log_10 2 ~= 500 xx 0.30103 = 150.515

So 2^500 ~= 10^150.515

Using an arbitrary precision calculator

sqrt(2)^1000 = 2^500
