Solutions
X = 9 - M.J
Yup. And you have 3 mans.--Tiggera 17:38, 28 Nov 2004 (MST)
Square Root of 81
Why does the article say 'If solved, X equals ±9.'? Isn't is exactly 9? Kvb 16:10, 9 Jun 2005 (UTC)
Multiply 9 x 9 ... you get 81. Multiply -9 x -9 ... what do you get? -- tomstiff 16:11, 9 Jun 2005 (UTC)
False Claims
The claim that x = 14 is the only solution making logx14 an integer is extremely false and I don't know why people insist on keeping that version of the article. Check it out, find a good calculator that can evaluate logb(n)14 for b(n) = 141/n for any integer non-zero integer n. In fact, (141/n)n = 14n/n = 141 = 14 which tells us that logb(n)14 = n for b(n) = 141/n.
