Final answer:
The numbers √-169 and √-64 are equivalent to 13i and 8i, respectively. The correct answer is -64 - 13i.
Step-by-step explanation:
The number √-169 is equal to 13i where i is the imaginary unit (√-1). This is because the square root of a negative number results in an imaginary number.
Similarly, the number √-64 is also equal to 8i.
Therefore, neither of the options A, B, or D is correct. The correct answer is option C, which is -64 - 13i.
