Final answer:
The value of n in the equation f(5x3) = 5 = 3 cannot be determined.
Step-by-step explanation:
To find the value of n in the equation f(5x3) = 5 = 3, we need to understand the concept of exponents.
In the given equation, 5x3 means 5 raised to the power of 3. So, we have f(5x3) = 53.
Now, if f(53) = 5 = 3, it means that 53 is equal to both 5 and 3. However, this is not possible because a number cannot be equal to two different values at the same time. Therefore, there is no value of n that satisfies the equation.
