Question

find the value of [503]by using suitable identity​

Answer 1

Answer:

the value of 503² by suitable identity = 253009

Step-by-step explanation:

We need to find the value of 503² by suitable identity

503² = (500 + 3)²

we can use here

(a + b)² = a² + b² + 2ab

a = 500

b = 3

(503)² = 500² + 3² + 2(500)(3)

=> (503)² = 250000 + 9 + 3000

=> (503)² = 253009

Answer 2

Answer:

503^2=253009

Step-by-step explanation:

(500+3)^2

(a+b)^2=a^2+b^2+2ab

a=500

b=3

(503)^2=500^2+3^2+2(500)(3)

503^2 =250000+9+3000

503^2=253009

here is the answer
