Anytime you forget exponent rules, try writing the whole thing out like this:

 

=   (2a3)4

 

=   (2a3)(2a3)(2a3)(2a3)

 

=   (2aaa)(2aaa)(2aaa)(2aaa)

 

=   (2 * 2 * 2 * 2) * (aaa * aaa * aaa * aaa)

 

=   24 * a12

 

=   16a12

 

And here's the shortcut method:

 

=   (2a3)4

 

=   24 a(3 * 4)

 

=   24 a12

 

=   16a12
