Question

Which expression is equivalent to

Answer 1

B)1/r^42, just simplify the expression using the rule of exponents

Answer 2

Answer: B.

Explanation:

When there is an exponent of another exponent, you can multiply them together:

As such, the expression in the image can be simplified to

`r^(-7*6)`, or r ^ -42.

Negative exponents can also be represented by positive exponents in the denominator of a fraction.

For instance,
`x^(-2)` can be rewritten as
`(1)/(x^2)`.

The correct answer is
`(1)/(r^(42) )`.
