See a solution process below:

Explanation:

First, rewrite the expression using this rule of exponents:

#a = a^color(blue)(1)#

#x^4/(2x) => x^4/(2x^color(blue)(1)#

Now, use this rule of exponents to divide the #x# terms:

#x^color(red)(a)/x^color(blue)(b) = x^(color(red)(a)-color(blue)(b))#

#x^color(red)(4)/(2x^color(blue)(1)) = x^(color(red)(4)-color(blue)(1))/2 => x^3/2#
