(2) 1

(3) (2N power of 3x) refers to 3 times of 2N power of x or 2N power of the whole 3x? If it is the former, the steps are as follows:

Solution: ∫x to the power of n =2, and n is a positive integer.

∴(3x to 2N) cube

=3? * (6N power of x)

= 27 * (n power of x) to the sixth power.

=27*(2 to the 6th power)

=27*64

= 1728

If it was the latter, I wouldn't do it.

The steps of the first two questions can't be written at all If you have to write, you can only simplify it.
