Since 1^n = 1 for all n, then √(2^6^2^1^n), n = 4^4 = √(2^6^2^1) = √(2^6^2) = √(2^36) = 2^(36/2) = 2^18 = 2^16 x 2^2 = 65.536 x 4 = 262.144 FYI, 2^16 is well- known as 16-bit color or pseudo color, has 65.536 colors combination.. Another well-known values are 2^8, 8-bit color or grayscale color has 256 colors, 2^10 or one kilobyte ie. 1.024, and 2^24, 24-bit color or true color, has 16.777.216 colors.

Pardonnez-moi d'exprimer mon étonnement quand je lis dans certains commentaires que c'est une belle démonstration ! Je vous propose donc de signaler TOUTES LES LOURDEURS INUTILES : 1°) 1^4^4 = 1, comme toute puissance de 1, il est inutile de calculer 4^4 2°) 2^1^4^4 = 2^1 = 2 , évidemment 3°) il reste donc rac( 2^(6^2)) = 2^(36/2)) = 2^18 . Attention au piège. Certes la racine carrée et l'élévation au carré se compensent, mais ici il est important de ne pas confondre, ce n'est pas 2^6 qui est au carré, c'est 2 qui est à la puissance 6^2. On évite le piège en mettant les parenthèses non écrites . Et bravo parce qu'elle n'a pas commis l'erreur. 4°) 2^18 = ? 5°) Écrire 2^9=2.2.2....2 est-ce vraiment utile ? Mais écrire 2^9 = (512)^2 c'est FAUX . Car 2^9 = 512. Etourderie ? Soyons clément. 6°) Calculer 512^2 en utilisant l'identité remarquable (a+b)^2, ça paraît bien joli, mais c'est lourd. C'est tellement plus simple de faire à la main la multiplication de 512x512 pour obtenir = 262 144. Jolies ongles et jolie bague. 😉
