is approximately 3.141592 and e is approximately 2.71828 so [tex]\pi^e= \pi^2 \pi^.718[tex], approximately. .718= 718/1000 and 1000 is close to . will be approximately 3.14 to the 718 power, then square root 10 times. That won't be very good approximation. You might see if you can find a higher power of 10 that is closer to a power of 2. Of course, that's going to be an awful lot of work!
