Question

( 2^{x+y}=6^{y} )
( 2^{x} cdot 2^{y}=6^{y} )
( 2^{x} cdot 2^{y}=(2 times 3)^{y} )
( 2^{x} cdot 2^{y}=x^{y} cdot 3^{y} )
( x^{2}-10 y^{3} )
( 2^{x}=3^{y} )
( log _{2}^{x}=log _{3} y )
( x log _{2}=y log _{3} )
( frac{x}{y}=frac{log 3}{log _{2}} )
( frac{x}{y}=log _{2}^{3} )

# 14. If 21+y = 6', then (a) 2log, 3 (b) log23 (c) log32 (d) none of these
