Question

Which can be used to solved the expression (r^-4)^3

Answer 1

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:

$(r^-^4)^3$

Properties of exponent:

$(x^m)^n=x^m^n$

$x^-^a=\frac{1}{x^a}$

Thus, we can simplify the given expression as:

$(r^-^4)^3$

= $r^-^1^2$

= $\frac{1}{r^1^2}$

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.
