(d) log log log x^(3)

Solve for x, (a) (log_(10)(x-3))/(log_(10)(x^(2)-21))=(1)/(2),(b)log(log x)+log(log x^(3)-2)=0; where base of log is 10 everywhere.

dx/(x*(lnx)ln(lnx).............................(ln ln ln ln.........lnx) larr20 times is equal to (i) (log log log log ..............x)larr 20times +C (ii) (log log log log ..............x)larr 19times +C (iii) (log log log log ..............x)larr 21times +C (iv) (log log log log ..............x)larr 22times +C

log(log x)+log(log x^(3)-2)=0; where base of log is 10 everywhere.

int (1)/( x (log x) log (log x) ) dx is equal to a) log (log x) + C b) log | log (x log x) + C c) log | log | log (log x) || + C d) log | log (log x) | + C

Equation log(log x)+log(log x^(4)-3)=0 has

int_( equal to )(dx)/(x(log x)(log log x)*(log log log*x)) is

Log (log i) =

Evaluate each of the following without using tables : (i) log 5 + log 8 - 2 log 2 (ii) log_(10) 8 + log_(10) 25 + 2 log_(10)3 - log_(10) 18 (iii) log 4 + (1)/(3) log 125 - (1)/(5) log 32

State, true or false : (i) log 1 xx log 1000 = 0 (ii) (log x)/(log y) = log x - log y (iii) If (log 25)/(log 5) = log x , then x = 2 (iv) log x xx log y = log x + log y
