Solve the logarithmic equation. Be sure to reject any value of x that is not in the domain of the original logarithmic expressio
KIM [24]

Answer:

Therefore x=9

Step-by-step explanation:

Give that,

log x+ log (x-3) = log 54

log x(x-3) =log 54             [    log_ca+log_c b=log_c(ab)   ]

x(x-3) = 54

Now expand the above equation to get a quadratic equation

x²-3x=54

⇒x²-9x+6x-54=0

⇒x(x-9)+6(x-9)=0

⇒(x-9)(x+6)=0

⇒x-9=0  or, x+6=0

⇒x=9,-6

Now putting x= -6 in the given expression,

log(-6)+log(-6-9)=log 54.

Since log (-6) does not exist.

Therefore x=9

Remember (x^m)(x^n)=x^{m+n}
so since they're all being multiplied, just add the exponents and see which one doesn't add to 2


A. -3+5-2+2=2+0=2, yep

B. -9+0+2+5=-9+7=-2, nope

C. -3-1+1+5=-4+6=2, yep

D. -5+9-2+0=4-2=2, yep
