3668 . P and Q are two positive integers such that PQ = 64 Which of the following cannot be the value of P +Q?

D. 65

Answer: Option C

Explanation:

To determine which of the following values cannot be the sum of P and Q,

we need to consider the possible factor pairs of 64. The factor pairs of 64 are:

= 1 * 64

= 2 * 32

= 4 * 16

= 8 * 8

For each factor pair, we can find the sum of P and Q:

P + Q = 1 + 64 = 65
P + Q = 2 + 32 = 34
P + Q = 4 + 16 = 20
P + Q = 8 + 8 = 16
So, the values of P + Q can be 65, 34, 20, and 16. Among the given options, the value that cannot be the sum of P and Q is 35.

Therefore, the answer is 35.
