Problema Solution

Which shows 522 - 482 being evaluated using the difference of perfect squares method?

522 - 482 = (2704 + 2304)(2704 - 2304) = 2,003,200

522 - 482 = (52 + 48)(52 - 48) = (100)(4) = 400

522 - 482 = 2704 - 2304 = 400

522 - 482 = (52 - 48)2 = (4)2 = 16

52^2 - 48^2 = (52 + 48)(52 - 48) = (100)(4) = 400
