Only 6 significant digits,
A more interesting result, perhaps:
pi^34 = 8.00010471505*10^16
The underlined digits match exactly the first five significant digits of pi/3. This leads to the polynomial
x^34 - (1/3)*10^12*x - 8*10^16 = 0
whose positive real root is
3.14159265364
Nice coincidence, isn't it?
Edited to correct a mistake in the second coefficient

returns a positive real root 3.14159265364. The wp 34s polynomial solver should return 3.141592653644187, but I haven't tested on it yet.
