Answer:

The expression is equal to 1 over 12 factors of r

Multiplying the exponents will create an equivalent expression.

Step-by-step explanation:

We are given the following in the question:

[tex](r^-^4)^3[/tex]

Properties of exponent:

[tex](x^m)^n=x^m^n[/tex]

[tex]x^-^a=\frac{1}{x^a}[/tex]

Thus, we can simplify the given expression as:

[tex](r^-^4)^3[/tex]

= [tex]r^-^1^2[/tex]

= [tex]\frac{1}{r^1^2}[/tex]

Thus, the correct answer is:

Option 2) The expression is equal to 1 over 12 factors of r

Option 4) Multiplying the exponents will create an equivalent expression.
