a) 2(-3a

^{2}b)^{2}=2 x (-3)^{2}x (a^{2})^{2}x (b)^{2}= 2 x 9 x a^{4}x b^{2}= 18a^{4}b^{2}

b)2b^{n}x 2^{3}b = 2 x 2^{3}x b^{n}x b = 2^{4}x b^{n+1}= 16b^{n+1 anyways I would always say to practice these sorts of exercises with the formulas that Reckoner gave here.} - June 6th 2012, 08:14 AMWilmerRe: Grade 9 Algebra help

It is letter A. Is this really a grade 9 equation?
