Answer:

#6^3# or as #216#

Explanation:

The laws if indices stay the same whether the indices are numbers or variables.

#x^-4 xx x^7# would be done by either

#1/x^4 xx x^7 = x^3" "or" "x^(-4+7) = x^3#

In exactly the same way:

#6^-4 xx 6^7 would be done by either

#1/6^4 xx 6^7 = 6^3" "or " " 6^(-4+7) = 6^3#

This can be given as #6^3# or as #216#
