Answer:
[tex] (5^3)^{-4} [/tex].
Step-by-step explanation:
According to the power rule, exponents can be multiplied when we have a number base that has an exponents which is raised to another power.
The following illustrates how to apply the power rule where multiplication of exponents is to be done:
[tex] (x^a)^b = x^{a*b} = x^{ab} [/tex], where, x is the base number, a and b are exponents respectively.
From the options given, the expression where the exponents are required to be multiplied is [tex] (5^3)^{-4} = 5^{3*-4} = 5^{-12} [/tex].
