[@backbencherarena6362]

Why we take (k+1)^3 or (k-1)^3 for prove summation of square natural??? Why we take (k+1)^4 or 4ab for prove summation of qube natura number?

[@animecodz8003]

Clearity of concepts that's all matter and u did it so well sir 😅

[@mahavirsinghshekhawat9]

Why we took ( k+1)^3 in equation 3 ?how we know it?

[@anitabehera1228]

My question is also same

[@shivanshuyadav7783]

Yes sir I also

[@AkhtarAli-hz8iq]

N3 ka matlab hai

[@aayushkumar5513]

Guyz you can also call it a trick
There are various other ways too to prove this result
The reason for taking (k+1)³ was that, it contained the required variables & consants to obtain the desired outcome

[@aayushkumar5513]

If you want to know how to realise that we should use (k+1)³ only, then expand the RHS & you'll know it all by yourself 😃

[@saleemmohd4939]

Thanks for education

[@chetabhatra]

Thank you sir ❤❤❤❤❤❤❤

[@khushisingh9672]
