Help needed in Syntax writing in MATLAB

Howdi all,
I'm trying to write the syntax for this formula but keep getting errors. Any help ? I belive it's happening due the complex number (i).

Post your code.

Thanks for your replay.
Well, If i'm using this syntax (Without the complex number) - It works :

>> (tanh(exp(log(3*pi)+log10(pi)))^3)/(7^8)

ans =

1.7347e-007

But as soon as I add the 'i' :

>> (tanh(exp(log(3*pi)+log10(pi)i))^3)/(7^8)
|
Error: Unexpected MATLAB expression.

Something went wrong.

--> (tanh(exp(log(3*pi)+log10(pi)*i))^3)/(7^8) 
                                                                                                   
ans =                                                                                                                                                 

1.7347e-007 +2.7977e-014i
