Question

(1) ( log _{4} x^{2}+log _{4} y+log _{4} 2=2 )
Similanly, ( x^{2} y z=16-0 )
- ( x y^{2} z=81 ) -
( x y z^{2}=256 ) (ii)
( Rightarrow quad(ln y z)^{4}=2^{4} cdot 3^{4} cdot 4^{4} )
( Rightarrow quad x y z=2 cdot 3 cdot 3 y=24 )
( x cdot x y z=16 )
( Rightarrow x=frac{16}{24}=frac{2}{3} )

# 24. (A) negative (B) equal to 2 (C) >2 (D) zero log2x + log4y + log4z = 2, logzy + loggz + loggx = 2 & log42 + log 16x + log169 = 2, then x = To tyl
