Identify the number that will replace the question mark in the second equation based on the relationship represented in the first equation.

420 92 602 456

456

The exponent power to a, b, c are (number of squares + 1) Thus answer is obtained as: \( {7 }^{3 } \) + \( {2}^{5 } \) + \( {3 }^{4 } \) = 343+32+81 = 456 The correct answer is Option (4) → 456
