Best ResponseYou've already chosen the best response.0Assuming I'm reading your expression correct, 3^3  (4m)/(m^2)  81... ...the only term you have to worry about is the 4m/(m^2) but note that the m in the numerator cancels out one of the power of m in the denominator so you have 3^3  4/m  81 So the only place the expression is undefined is m = 0. Hope that helps!

Best ResponseYou've already chosen the best response.0begin with denominator equal zero  so because you know that one fraction than will be undefined sure  so than ther will be (m9)(m+9)=0  so m9=0 so m=9 and m+9=0 so m=9  than result that for m=+/ 9 this fraction will be undefined sure

Best ResponseYou've already chosen the best response.0^ plugging 9 and 9 into the expression gives real numbers 3^3  4(9)/(9^2)  81 = 9  36/81  81 = 652/9 3^3  4(9)/(9^2)  81 = 9 + 36/81  81 = 644/9 The expression is only undefined when m=0.
