Question

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

Answer 1

The expression is equal to 1 over 12 factors of r

Multiplying the exponents will create an equivalent expression.

Explanation:

We are given the following in the question:

`(r^-^4)^3`

Properties of exponent:

`(x^m)^n=x^m^n`

`x^-^a=(1)/(x^a)`

Thus, we can simplify the given expression as:

`(r^-^4)^3`

=
`r^-^1^2`

=
`(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.
