thank u brother
welcome
was everything clear?
you must know the properties of integral powers, cause I realised I forgot to give them in brackets at necessary places
but you must give them to get step marks
like in the step where I added the powers and took a common base 2, must write in a bracket the property -> a^m + a^n = a^(m+n), or however it is stated in your prescribed book
