Solution

Sure, let's solve this step by step:

  1. First, we need to understand that 738\sqrt[8]{7^3} is the same as 73/87^{3/8}. This is because the nth root of a number can be expressed as that number raised to the power of 1/n.

  2. Now, we have the equation 7a=73/87^a = 7^{3/8}.

  3. Since the bases (7) are the same, the exponents must also be equal. Therefore, we can set a equal to 3/8.

  4. So, a=3/8a = 3/8.
