Question

Using identities find 51² = 49²​

Answer 1

Answer:

51²-49²

now this can be solved using identity a²-b² = (a+b)(a-b)

ie (51+49)(51-49)

= (100)(2)

= 200

Answer 2

Answer:

hey mate here's your answer!!!!

Step-by-step explanation:

for this sum we can use the identity (a+b)(a-b) =a^2 - b^2

so here (51+49)(51-49)=51^2 - 49^2

which means the answer is (100)(2)

so your answer is 200
