Question

evaluate 98°by using (a-b) 2 identify​

Answer 1

Answer:

Hey here is my answer

Step-by-step explanation:

We can write (98)^2 as ( 100 - 2)^2

Therefore it is our (a-b) ^2 Identity!

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

= 10000 + 4 - 400

Which is equal to

=10004-400 = 9604

Therefore 98^2 = 9604

Kindly mark as brain list!
