Question

Решите логарифмический пример

Answer 1

$1) (2^{log_27})^{log_725} = 7}^{log_725} = 25$

$2) log_354-log_2 sqrt{2} - log_32 = log_3 frac{54}{2} - frac{1}{2} = log_33^3- frac{1}{2} = 3- frac{1}{2} = 2,5$

Answer 2

1)
2^(log_2(7))=7
7^(log_7(25))=25
2)
log_2(sqrt(2))=1/2
log3(54/2)=log_3(27)=log_3(3^3)=3
3-1/2=5/2=2,5
