Step-by-step explanation:
Given problem: Â Expand the following logarithm completely:
→  ] ;
_________________________________________
To begin: Â Simplify:
  →   ]  ;
_________________________________________
First, within the "numerator" ,  rewrite:  " √(y² - 1) " ;  as:
     "  " ;
→  Note the following property of exponents:
      ;
_________________________________________
Then rewrite the expression as:
  Â
Note the "quotient rule" property of the "natural logarithm (ln)" ;
     ln (a/b)  = ln a − ln b ;
So; we have:
   ;
 ↔ Â
 -
  ln ;
_______________________________________________
  ln a = ln   ;
  ln b = ln ;
Simplify:  ln a − ln b  ;
_______________________________________________
First, simplify: Â ln a ; Â
   ln a = ln   ;
→  Note the "product rule" for the "natural logarithm" {" ln " }:
 →   ln(a * b) = ln(a) + ln(b) ;
 →   ln (  * ) ;
       in which:
        a = ;
        b = ;
→  ln (a * b) =
  (ln a  +  ln b ) =
   =  [ ln ()] + [ ln [ = ? ;
First, simplify: Â "ln a " ;
→ ln a = ln = ? ;
→  Note the "product rule" for the "natural logarithm" {" ln " }:
 →   ln(a * b) = ln(a) + ln(b) ;
 →   ln {27 *x^{3}) = ln 27 + ln x³  ;  in which:  a = 27 ; b = x³  ;
 →   ln(a * b) = ln(a) + ln(b) = ln 27 + ln (x³)  = ?  ;
Note:  We have "x³ " ;  Note the number:  "27" ;  the ∛27 = 3 ; a whole number integer; so rewrite "ln 27" as:  "ln (3³)"
 →   ln(a * b) = ln(a) + ln(b) = ln 27 + ln (x³) = ln (3³) + ln (x³) ;
                                   =  3 ln 3 + 3 ln x . Â
So;  "ln a " from above:  →  ln(a * b) =  (ln a + ln b) ;
   =  [ ln ()] + [ ln [  = ? ;
→ Rewrite:  (3 ln 3 +  3 ln x) + [ln [ = ? ;
Now, find simplify the following "ln b" from above:
→ ln b = ln  [ = (0.5) ln (y² -1) ;
Rewrite:  →   ln(a * b) = ln(a) + ln(b) = ln 27 + ln (x³) ;
   = (3 ln 3 +  3 ln x) + [ln [ =
   = (3 ln 3 +  3 ln x) +  0.5 (ln [) ;

So, this is the value for the "ln" of the "numerator" of the given problem:
" (3 ln 3 + Â 3 ln x) + Â 0.5 (ln [) " .
_____________________________________
Now, let's find the value for the "ln" of the "denominator" of the given problem:
_____________________________________
 →  " ln y(x -1)²  " ;
 =  ln * ;
→ Use the product rule:  ln(a * b) = ln a + ln b ;  a = "y" ;  b = " (x-1)² " .
→  ln (*)  = (ln y) * (ln (x-1)²) ;
Note:  ln (x-1)² = 2 ln (x-1) ;
→ (ln y) * [ ln (x-1)² ] =  (ln y ) * 2 ln (x-1) = 2 (ln y) [ ln (x-1) ] .

So, going back to our original given problem:

→  ;
 Â
→  Use the "quotient rule" property of the "natural logarithm (ln)" ;
     ln (a/b)  = ln a − ln b  ;
Note: Â " ln a " Â = " Â (3 ln 3 + Â 3 ln x) + Â 0.5 (ln [)
      "ln b " =  " (2 (ln y) [ ln (x-1) ]
