→ which, when 'read aloud' ; is:  "What is log base ten of 100" ?
____________________________________________________
→  To solve:
____________________________________________________

→  " log₁₀ 100 = x " ;   →  Solve for "x" ; 

→ 10ˣ = 100 ;  Solve for "x" ; 
 
→  that is;  "10 raised to the "x th" power" = 100 " ;    →  Solve for "x" ; 

→  The answer:  "x = 2 " ; 

→  {since:  " 10² = 100" ; since:  "10 * 10 = 100" } ; 

→  log₁₀ 100 = " 2 " ;   →  which is:  Answer choice:  [C]:  " 2" .
