`log(11/7)^5=5log11/7`

log_5 2log_(11) 5log_(32) 11

Which of the following numbers are non positive? (A) 5^(log_(11)7)-7(log_(11)5) (B) log_(3)(sqrt(7)-2) (C) log_(7)((1)/(2))^(-1//2) (D) log_(sqrt(2)-1) (sqrt(2)+1)/(sqrt(2)-1)

The value of log (14/3) + log (11/5) - log (22/15) is:

Log_(7)5=

the value of 5^(log_(7)11)-11^(log_(7)5) is

log((11)/(5))+log((14)/(3))-log((22)/(15))=log7

if a,b,c are positive real numbers such that a^(log_(3)7)=27;b^(log711)=49 and c^(log_(11)25)=sqrt(11) then the value of {a^(log_(3)7)sim2+b^(log_(7)11)^^2+c^(log_(11)25)^^2} is

Which of the following are correct? a. (log)_3 19.(log)_(1//7)3.(log)_4 1/7>2 b. (log)_5(1//23) lies between -2 &-1 c. \ If m=4^((log)_4 7)a n d\ n=(1/9)^(-(log)_3 7)t h e n\ n=m^4 d. (log)_(sqrt(5))sin(pi/5)dot(log)_(sqrt(sin(pi/5)))5 simplifies to an irrational number
