Решение: ^ - здесь степень V - корень квадр. Д4.12 log 5 (7-x) = log 5 (3-x) + 1 log 5 (7-x) = log 5 (3-x) + log 5 (5) log 5 (7-x) = log 5 [5*(3-x)] 7-x = 5*(3-x) 7-x = 15 - 5x 5x = 8 x = 5/8 Д4.11 log (x-5) 49 = 2 (x-5)^2 = 49 x^2 - 10x + 25 = 49 x^2 - 10x - 24 = 0 x(1) = 12 x(2) = - 2 Д4.10 2^(3+x) = 0,4 * 5^(3+x) 2^3 * 2^x = 2/5 * 5^3 * 5^x 2^3 * 2^x = 2 * 5^2 * 5^x 2^x /5^x = 2/2^3 * 5^2 (2/5)^x = (5/2)^2 (2/5)^x = (2/5)^(-2) x = -2 Д4.9 (1/3)^(3+x) = 9 [3^(-1)] ^(3+x) = 3^2 3^ (-3-x) = 3^2...
