Answer:

We can use a rule of exponents to simplify this expression. See full explanation below

Explanation:

We can use the following rule for exponents to simplify this expression to use only positive exponents:

#z^b = 1/z^b# and therefore #1/z^-b = z^b#

Applying this to the expression in the problem gives:

#-2xa^4# or #-2a^4x#
