Final answer:
There is no solution for the equation 7a = 787a = 87⁷, so we cannot calculate the value of aᵃ.
Step-by-step explanation:
To find the value of aᵃ, we can use the given equation 7a = 787a = 87⁷.
First, let's solve for the value of a. From the equation 7a = 787a, we can cancel out the a on both sides of the equation, leaving us with 7 = 787. However, this is not possible because 7 is not equal to 787. Therefore, there is no solution for a.
Since there is no value of a, we cannot calculate the value of aᵃ.
