Answer 1

Answer:

A. 328

Sum of Cubes of Digits of First Number - Sum of Squares of Digits of First Number = Second Number (2^3 + 3^3 + 4^3) - (2^2 + 3^2 + 4^2) = (8 + 27 + 64) - (4 + 9 + 16) = 99 - 29 = 70 Similarly; (5^3 + 4^3 + 6^3) - (5^2 + 4^2 + 6^2) = (125 + 64 + 216) - (25 + 16 + 36) = 405 - 77 = 328
