 629926.  Mon Oct 26, 2009 3:53 pm 382 = ( Γ(Γ(4)) − 4! ) × 4 − √4Last edited by Sophie.A on Mon Oct 26, 2009 7:00 pm; edited 3 times in total 629976.  Mon Oct 26, 2009 6:14 pm Vera C wrote: 381 = ( Γ(Γ(4)) + 4 + T(4) ) * T(4) Is that right?

Close.. but no (you missed out some root signs - giving a result of 1340).
381 = ( Γ(Γ(4)) + 4 + T(√4) ) * T(√4) 629990.  Mon Oct 26, 2009 6:54 pm Thanks. 383 = ( Γ(Γ(4)) − 4! ) × 4 − Γ(√4) 629994.  Mon Oct 26, 2009 7:00 pm 384 = ( Γ(Γ(4)) − 4! ) × 4 629995.  Mon Oct 26, 2009 7:03 pm 385 = ( Γ(Γ(4)) − 4! ) × 4 + Γ(√4) 629996.  Mon Oct 26, 2009 7:06 pm 386 = ( Γ(Γ(4)) − 4! ) × 4 + √4 629997.  Mon Oct 26, 2009 7:07 pm 387 = ( Γ(Γ(4)) − 4! ) × 4 + T(√4) 629998.  Mon Oct 26, 2009 7:08 pm 388 = ( Γ(Γ(4)) − 4! ) × 4 + 4 630000.  Mon Oct 26, 2009 7:09 pm 389 = ( Γ(Γ(4)) − 4! ) × 4 + 4 + Γ(√4) 389 = (4² + T(4))² + 4! + 4Last edited by Vera C on Thu Oct 29, 2009 7:20 am; edited 2 times in total 630749.  Thu Oct 29, 2009 2:37 am 390 = (4! x 4²) + 4 + √4 630750.  Thu Oct 29, 2009 2:53 am Vera C wrote: 389 = ( Γ(Γ(4)) − 4! ) × 4 + 4 + Γ(√4)

I know it seems unfair for me to point out a possible error when I haven't a clue how to correct it, but isn't that one digit 4 too many? 630785.  Thu Oct 29, 2009 7:11 am Yes, you're quite right. Thanks for pointing it out. I've changed it to something better. 391 = (4! x 4²) + 4 + T(4) 630960.  Thu Oct 29, 2009 7:03 pm 392 = 4! * 4^√4 + 4!! 632810.  Tue Nov 03, 2009 6:23 pm This is all perhaps getting a bit too easy. How about trying three 3s? http://z6.invisionfree.com/qigames/index.php?showtopic=6 762322.  Wed Nov 24, 2010 10:20 am Vera C wrote: Yes, you're quite right. Thanks for pointing it out.

To correct Vera: (4! x 4²) + 4 + T(4) = 398, not 391.

391 = T(T(gamma(4)))+sqrt(sqrt(sqrt(4^4!)))/.4
392 = 4*(4*4!+sqrt(4)) Page 3 of 4
