I have exams coming up soon and I'm just going through my textbook and practising a few past exam papers and I have this which I need help on.
b) 2bn x 23bThanks in advance!!!!!
a) 2(-3a2b)2=2 x (-3)2 x (a2)2 x (b)2 = 2 x 9 x a4 x b2 = 18a4b2
b)2bn x 23b = 2 x 23 x bn x b = 24 x bn+1 = 16bn+1
anyways I would always say to practice these sorts of exercises with the formulas that Reckoner gave here.
It is letter A. Is this really a grade 9 equation?
