Question

what is the value of antilog(-4.15 how it is done?

Answer 1

Log is 10 base  

If  log 10 x= y  

Then antilog y=x  

Or 10y=x 

So antilog (-4.15) = 10 raise to power –4.15 = 1/10  raise to power 4.15 

= 1/(10 raise to power 4 x 10 raise to power 0.15) 

=1/(10 raise to power 4 x 10 raise to power 15/100) 

= 1/(10 raise to power 4 x (10 raise to power 15) raise to power 1/100) 

= 7.08 x 10 raise to power –5 

(In order to find out the value of log, antilog you can use log table/scientific calculator)
