Question

For how many distinct real values of \( x \) does the equation below hold true? (Consider \( a>0 \)) \[ x^2 \log_a (16) - \log_a (64) \div \log_a (32) - x = 0 \]

• A. 1
• B. 0
• C. Depends on the value of \( a \)
• D. 2
• E. Infinitely many

Hint:

Logarithmic equations often depend on the base, so check for any restrictions or relationships that affect the number of solutions.
