Explanation:

You can use this rule of exponents to simplify this expression: #(x^color(red)(a))^color(blue)(b) = x^(color(red)(a) xx color(blue)(b))#

#(x^color(red)(-4/7))^color(blue)(7) = x^(color(red)(-4/7) xx color(blue)(7)) = x^(color(red)(-4/cancel(7)) xx color(blue)(cancel(7))) = x^-4#

If you want the expression with no negative exponents you would use this rule for exponents: #x^color(red)(a) = 1/x^color(red)(-a)#

#x^color(red)(-4) = 1/x^color(red)(- -4) = 1/x^4#
