 * I have expressed [this equation](https://imgur.com/3xGgy3c) as
 *     ```
       POW(POW(1+(fieldname16/fieldname33),1/fieldname35-1),fieldname35)-1
       ```
   
 * where fieldname16=P. fieldname33=A and fieldname35=q,
 * but I keep on getting a wrong answer. Please could you help me in correcting 
   my expression?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fequation-edit%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello [@graicifyd](https://wordpress.org/support/users/graicifyd/)
 * No, your equation is incorrect. You are grouping fields in the wrong way. The
   correct would be:
 *     ```
       POW(POW(1+fieldname16/fieldname33,1/fieldname35)-1,fieldname35)-1
       ```
   
 * Best regards.

 * Please could you also help confirm if this is correct?
 * `log[ 1 + (1/N) ] / log2`
 * Expression:
 * LOG(1+(1/fieldname36))/LOG(2)
 * fieldname26 = N
 * Thanks in advance.

 * Hello [@graicifyd](https://wordpress.org/support/users/graicifyd/)
 * The answer is …depends…
 * If you want to get the log base 10, you cannot use the LOG operation because 
   in javascript the LOG operation returns the logarithm base “e”. If you want to
   calculate the logarithm base 10, you should use the LOGAB operation distributed
   with the plugin: LOGAB(X, Y) returns the logarithm of X base Y, in whose case
   the operation would be:
 *     ```
       LOGAB(1+(1/fieldname36), 10)/LOGAB(2, 10)
       ```
   
 * All these operations are described in the documentation page of the plugin:

 * Best regards.
