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) × (-3 + 2 )
-6 × (-6)
36

b. ( -10 × (-3) ) = 30
( 10 × 2 ) = 20
( 10 x (-5) = - 50

30 + 20 + (-50) × -5 - (-3) + 2
0 × -5 +3 + 2
0

Answer 2

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 (-5 + 3 +2)
0 x 0 = 0
c. ( 2(9)(4) - (-20) x (2 + (-)(-5) - (-3))
(72 + 20) x (2 + 5 + 3)
92 x 10 = 920
d. (3(9)(2) + 2(-3)(2) - 3(9)(-5)) x (9 + (-5) -4)
(45 + (-12) - (-135) x (0)
188 x 0 = 0
e. (2(-3)(2) - 3(25)) x (-6 - (-5))
(-12 -75) x (-1)
-86 x (-1) = 87
