Question

evaluate using formula (196)²​

Answer 1

Step-by-step explanation:

Given (196)

2

We have (a−b)

2

=(a

2

−2ab+b

2

)

(196)

2

can be written as 200−4

So here a=200 and b=4

Using the formula,

(200−4)

2

=(200

2

−2×200×4+4

2

)

On simplifying we get

(200−4)

2

=(40000−1600+16)

(196)

2

=38416

Answer 2

Answer:

(196)^2 = (200 - 4)^2

Step-by-step explanation:

==> (200)^2 + (4)^2 - 2*200*4

==> 40000 + 16 - 1600

==> 38416
