Thank you
May i check if this qn can be solved using a³-b³ method? Im not sure how to use for this qn
My pleasure. To your question, yes you can. I would however use binomial expansion or the pascal triangle to crack this because it does not, in my humble opinion, worth the effort to memorise the formula for a^3 - b^3. Regards
