Question

evaliate 98 square using suitable identity of algebra

Answer 1

Answer:

98 square

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

Answer 2

98 square using suitable identity of algebra

• Given,
• 98
• = (98)^2
• =(100-2)^2
• Identity (a-b)^2 = a^2 + b^2 - 2ab
• (100-2)^2 = 100^2 + 2^2 - 2(100)(2)
• = 10000 + 4 -2(200)
• = 10004 - 400
• = 9604
• ∴  (98)^2 = 9604
