Question

please give me answer please​

Answer 1

Answer:     (52)^2 = 2704

                   (98)^2 = 9604

                   (998)^2=996004

Step-by-step explanation:

(100-2)^2 = (100)^2 + (2)^2 - 2(100)(2)

= 10000 + 4 - 400

Which is equal to

=10004-400 = 9604

(a−b)  ^2  =a ^2 −2ab+b^ 2

 we get,

=(1000)^  2  −2(1000)(2)+(2) ^2

 =1000000−4000+4

=996004
