Question

Jika A = -3, B = 2, C = -5, Hitunglah Nilai Dari :
a. ( a + b + c ) x ( a + b )
b. ( -10a + 10b + 10c ) x ( c - a + b )
c. ( 2a²b² - 4c ) x ( b + ( -c ) - a )
d. ( 3a²b + 2ab - 3a²c ) x ( a² + c - b² )
e. ( 2ab - 3c² ) x ( ab - c )

Answer 1

A. (-3+2+(-5)) x (-3+2) = (-6) x (-1) = 6
b. (-10(-3) + 10(2) + 10(-5)) x (-5 - (-3) + 2) = (30 + 20 - 50) x (0) = 0
c. (2(-3)²(2)² - 4(-5)) x (2 + 5 - (-3)) = (2(9)(4) + 20) x (10) = (72 + 20) x (10) = 920
d. (3(-3)²(2) + 2(-3)(2) - 3(-3)²(-5) x ((-3)² + (-5) - (2)²) = (54 - 12 + 135) x (9 - 5 - 4) =
