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) ).
