Question

Diketahui a = 3, b= 2 dan c = 1 , tentukanlah :
a. nilai T , jika T = a² - 2ab + bc
b. nilai A , jika A = 2ab - bc
c. nilai N , jika N = abc + abc²
d. nilai E , jika E = ab - bc - ac
e. nilai I , jika I = a pangkat 3 - 2 bc + c²

Answer 1

A. T = 3² - (2x3x2) +(2x1) = 9 - 12 + 2 = -1
b. A = (2x3x2) - (2x1) = 12 - 2 = 10
c. N = (3x2x1) + (3x2x1²) = 6 + 6 = 12
d. E = (3x2) - (2x1) - (3x1) = 6 - 2 - 3 = 1
e. I = 3³ - (2x2x1) + 1² = 27 - 4 + 1 =24
