How to calculate the percentage transmittance given the absorbance and a formula.?

Given the absorbance = .081



How do we calculate the percent transmittance given the formula:



A=-log(%T/100)



P.S. I really don't remember how logs work so please help me somebody :( Thanks.How to calculate the percentage transmittance given the absorbance and a formula.?
Solving for %T:

10^-A = 10^(log(%T/100));

10^-A = %T/100;

100*10^-A = %T.

Substituting,

100*10^-0.081 = %T = 83.0.How to calculate the percentage transmittance given the absorbance and a formula.?
Can u plzzzzzz tell me how you got the perecentage?

100*10^-0.081 = %T = 83.0.
