Answer 1

Answer:

$\large\boxed{\sf{1601}}$

Step-by-step explanation:

Relation: 4@3 = 145

Reason : 4×3 = 12 => 12×12 = 144 => 144+1 = 145

Relation: 7@2 = 197

Reason: 7×2 = 14 => 14×14 = 196 => 196+1 = 197

Relation: 5@4 = 401

Reason: 5×4 = 20 => 20×20 = 400 => 400+1 => 401

Relation: 8@5 = ??

Reason: 8×5 = 40 => 40×40 = 1600 => 1600+1 = 1601

Hence, 1601 is the answer.
