(B) To evaluate $78 	imes 84$ using algebraic identities,we can express the numbers as:$78 = (80 - 2)$$84 = (80 + 4)$Using the identity $(x + a)(x + b) = x^2 + (a + b)x + ab$,where $x = 80$,$a = -2$,and $b = 4$:$(80 - 2)(80 + 4) = (80)^2 + (-2 + 4)(80) + (-2)(4)$$= 6400 + (2)(80) - 8$$= 6400 + 160 - 8$$= 6560 - 8$$= 6552$
