kindly while solving problems in thermodynamics chemistry we require to evaluate the value of 20 to the power 1.4and 5 to the power of 1.4. kindly let me know to solve such numerical power without using logarithms and scientific calculator. this will be of great help while solving numericals in thermodynamics.

Dear student
 
you can use log
 
let y = 20^1.4
 
log y = 1.4 log 20
 
y = 10^(1.4 * 1.3010)
 
similarily use with 5^1.4
 
also please take approximation as approximation would help us a lot
