ответ 2. Методом тыка


vavbasj: то есть, просто подставляя числа? Других способов не существует?
akimenkoola173: Конечно есть, я думала, Вам срочно нужно, сейчас объясню. степень приравниваем, т. е. 2+х=(1296 возводим в степень, т. е. 6) 2+х=6; х=4. Уж легче методом подстановки
akimenkoola173: 2+х=4 (Т.к. 6 в 4 степени), х=2
