используются формулы
log(a) bc = log(a) b + log(a) c
a^(log(a) b) = b
1. 2,4^(log(2,4) 8) - 7 = 8 - 7 = 1
2. 43.2^(log(3.2) 7) это равно 43.2^1.67 = 538.59
описка в задании или задание 43.2^(log(43.2) 7) или 3.2^(log(3.2) 7) в обоих ответ одинаковый и равен 7
3. log(5) 75 + log(5) (25)^-1 = log(5) 75 + log(5) 1/25 = log(5) 75/25 = log(5) 3
4. 9^(log(9) 6) : log(5) 25 = 6 : 2 = 3
5. log(5) 25c = log(5) 25 + log(5) c = 2 + log(5) c = 2 + 17 = 19
log(5) c = 17
