Logarithmic Equations -

\\\mathrm{Equation \;of \;the \;form \; log_{\; a}f(x) = b \; (a>0), a \neq 1,} \\\mathrm{is\;known \;as\; logarithmic\; equation.} \\\mathrm{this\; is\; equivalent\; to\; the \; equation\; f(x)=a^b\; (f(x)>0) }

 

If the given equation is in the form of f (loga x) = 0, where a > 0 and a is not equal to 1.

In this case, put loga x = t and solve f(t) = 0.

 

-

this inequation is equivalent to:

 

\\\mathrm{(2(x^2-10x+24))\geq(x^2-9)} \\\mathrm{x^2-9>0} \\\mathrm{x-3>1} \\\mathrm{on\;solving\; these\; equation\; we \; get} \\\mathrm{x\in[10+\sqrt{43}, \infty)}

 

option (d) is correct
