    if the total score of the 12 student class is x then x/12=70 and x=70×12=840 similarly if the total test score of the 18 student class is y then y18=80 so y=18×80=1440 the total combined is 1440+840=2280 so the average over the 30 students is 2280/30=76

    U all should know that sum of all the complex roots of a number is always 0(zero) means 1+w+2 = 0 and x^2 = 4 so x = +2 or x = -2 2-2 =0 or x^3 = 5^3 so x = 5,5w,5w^2 sum of them is zero same would be for roots of X^7 = 7 and so on sum of roots should be zero whether there are two...
