Question

Determinen el valor de las expresiones considerando el valor de n.
n=3
3n(4n³—2n²)+12-4=
n(12n-3n)+2n-n=
(n/4+2n/4)3n=

Answer 1

3(3) [4(3^3) - 2(3^2)] + 12 - 4 =
9[4(27) - 2(9)] + 8 =
9(108 - 18) + 8 =
9(90) + 8 =
810 + 8 = 818

3[12(3) - 3(3)] + 2(3) - 3 =
3[36 - 9] + 6 - 3 =
3[27] + 3 =
81 + 3 = 84

[(3/4) + 2(3)/4] 3(3) =
[3/4 + 6/4] 9 =
[9/4] 9 = 81/4
