Question

Evaluate 893^2-892^2, using a suitable identity

Answer 1

Answer:

here is your Answer

identity used: a²-b² = (a+b ) (a-b)

893²-892²= (893+892) (893-892)

893²-892²= 1785× 1

893²-892²=1785

Answer 2

893^2 - 892^2

a^2 - b^2 = (a+b)(a-b)

893^2 - 892^2 = (893+892)(893-892)

= 1785 ( 1 )

= 1785
