Question

( (log x+log (x-1))(log (x-1)-lg x) )
( +left(log _{2} xright)^{2}=4 )
( (log (x-1))^{2}-left(log _{2} xright)^{2}+left(lg _{2 x} x^{2}=4right. )
( log _{2} x-1=pm 2 )
( x-1=4, frac{1}{4} )
( x=5,5 / 4 )

# TU Multiple Correct Answer Type (4 Marks each. -1 for wrong answer) 8. The possible value(s) of x, satisfying the equation log,(X-X)092| + (log,x)2 = 4, isare) (B) 5
