if (log P)/2 = (log_(q))/4 = (logr)/8 = k nad pqr =100, then k = ______

(b) If (log a)/(q-r)=(log b)/(r-p)=(log c)/(p-q) , prove that a^(p)b^(q)c^(r)=1

If (log a)/(q-r)=(log b)/(r-p)=(log c)/(p-q) prove that a^(p)b^(q)c^(r)=1

If (log x)/(q-r)=(log y)/(r-p)=(log z)/(p-q) prove that x^(q+r)*y^(r+p)*z^(p+q)=x^(p)*y^(q).z^(r)

log_(a)((P)/(Q))=log_(a)P-log_(a)Q

10^(log_p(log_q(log_r(x))))=1 and log_q(log_r(log_p(x)))=0 , then 'p' is equals

If (log_(a)x)/(log_(ab)x)=4+k+log_(a)b then k=

If p^(th), q^(th), r^(th) terms of a geometric progression are the positive numbers a,b,c respectively, then the angle between the vectors (log a^(2)) I + (log b^(2)) j + (log c^(2))k and (q - r) I + (r - p) j + (p - q) k is
