Which shows 52^2 - 48^2 being evaluated using the difference of perfect squares method?

Question

mathmate · Answer

Hint: use the identity:
$(a+b)(a-b)=a^2-b^2$

anonymous · Answer

$52^2-48^2=(52+48)(52-48)=\dots$

anonymous · Answer

my bad 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

the choices

Don't you mean:
$$52^2 - 48^2 = (2704 + 2304)(2704 - 2304) = 2,003,200$$$$52^2 - 48^2 = (52 + 48)(52 - 48) = (100)(4) = 400$$$$52^2 - 48^2  = 2704 - 2304 = 400$$$$52^2 - 48^2 = (52 - 48)2 = (4)2 = 16$$ Its a bit misleading when you write it the way you did above...
