Final answer:
To find the equivalent expression, subtract the exponents and simplify the result.
Step-by-step explanation:
The graph of an exponential function depends on whether it represents growth or decay. Growth graphs rise from left to right, while decay graphs fall.
When dividing exponential expressions with the same base, you subtract the exponents. Therefore, 13⁶ / 13⁸ / 13⁻⁴ / 13⁻² is equivalent to 13^(6 - 8 - (-4) - (-2)). Simplifying the exponents, we get 13^(-2). This can be written as 1/13² or 1/169.
