Question

lip ( log _{x} y= )
logy ( x ) - 1 bay both the sudus ( log (x)^{2}=y^{2} )
( left[log _{y} xright]^{2}+[log x y]^{2}+2=49 )
( left(log _{4} xright)^{2}+left(log _{x} yright)^{2}=47 )
Optorn ( c )

# 3. If log, x + log, y = 7, then the value of (log,x)+ (log,y)', is (A) 43 (B) 45 (D) 49 If log (log (log(x)= 0 log (log (log.(v))) = () and log (log (log.(z))) = 0 then the sur (C) 47 4.
