(x)quad log_(7)1

Evaluate: log_(7)1

Evaluate: log_(7)((1)/(343))

Determine the values of the following. (iv) log_(7)1

Write the following relation in expontial form and find the values of respective variables. (iv) log_(7)""(1)/(343)=-a

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)

For x>2,quad if log_((1)/(7))(3^(x)+2x-5)=x(1-log_(7)21) then x=

(d)/(dx)log_(7)(log_(7)x)= (a) (1)/(x log_(e)x) (b) (log_(e)7)/(x log_(e)x) (c) (log_(7)e)/(x log_(e)x) (d) (log_(7)e)/(x log_(7)x)

Domain of the function is : phi(x)=log_(7)(-log_((1)/(2))(1+(1)/(root(4)(x)))-1)

Solve for x, if : log_(x)49 - log_(x)7 + "log"_(x)(1)/(343) + 2 = 0 .

The value of (1/(log_(5)210) + 1/(log_(6) 210) + 1/(log_(7)210)) is:
