Explanation
To solve this problem, we need to determine the pattern used in the '@' operator.
Looking at the given examples:
• 5@6=61, we can observe that (5^2)+(6^2)=61
• 8@10=164, we can observe that (8^2)+(10^2)=164
Therefore, the pattern seems to be: (first number)^2 + (second number)^2 = result
Using this pattern, we can find the value of 7@9 as follows:
• 7@9 = (7^2) + (9^2) = 49 + 81 = 130
Hence, the answer is option C: 130.
