Question

Solve (200)^2 +(100)^2 using identities

Answer 1

Answer:

final value is 50000

Step-by-step explanation:

we have given

(200)^2+(100)^2 = (2×100)^2+(100)^2

Using identity of exponential, we get

 = 2^2×100^2 + 100^2

take common term outside

= 100^2 ( 2^2 + 1) = 10000 (4+1)

= 10000 × 5 = 50000

Answer 2

Answer:

(200)²+(100)²=50,000

Step-by-step explanation:

✧To Find:-

  (200)²+(100)²

✧ Formula Applied:-

   a²+b²=(a+b)²-2ab

✧ Solution:-

⇒(200)²+(100)²

⇒(200+100)²-[2×(200)×(100)]

⇒(300)²-(400×100)

⇒90,000-40,000

⇒50,000
