The easiest way to print a prime symbol in a latex document is to use a prime(') symbol or \prime command. Then you understand that for double prime you have to use the symbol or command twice at the same time.

   \[ f''(x) \]
   \[ f^{\prime\prime}=\frac{d^2 f}{dx^2} \]
   % Use \newcommand for create custom command
   \[ f\dblprime \]
   \[ f\dblprime_{xy}(x,y) \]
   \[ 18^\prime 36\dblprime 16 \]
   \[ 1^\prime 33\dblprime 02 \]

Output :

Use double prime symbol without package.

Different packages already have macros defined for this symbol. For example the stix package.

   \[ f^\dprime \]
   \[ f^\dprime(x) \]
   \[ f^\dprime=\frac{d^2 f}{dx^2} \]

Output :

Use double prime symbol with stix package.
