The answer is #x^12#.

Explanation:

Write out the whole power of #4#, then add up the exponents using the exponent addition rule. I color-coded some of the problem so that it is easier to see:

#color(white)=(x^3)^4#

#=(x^color(red)3)(x^color(yellow)3)(x^color(green)3)(x^color(blue)3)#

#=x^color(red)3*x^color(yellow)3*x^color(green)3*x^color(blue)3#

#=x^(color(red)3+color(yellow)3)*x^color(green)3*x^color(blue)3#

#=x^color(orange)6*x^color(green)3*x^color(blue)3#

#=x^(color(orange)6+color(green)3)*x^color(blue)3#

#=x^color(brown)9*x^color(blue)3#

#=x^(color(brown)9+color(blue)3)#

#=x^12#
