Answer 1

• Diketahui :

x = 5

y = 6

• Ditanya :

x + x³ - y(2) × y(x) = ...?

• Jawab :

x + x³ - y(2) × y(x)

5 + 5³ - 6(2) × 6(5)

5 + ( 5 × 5 × 5 ) - 12 × 30

5 + ( 25 × 5 ) - 12 × 30

5 + 125 - 12 × 30

5 + 125 - 360

130 - 360

-230

Answer 2

x + x³ - y(2) × y(x)

x → 5

y → 6

x + x³ - y(2) × y(x)

= 5 + 5³ - 6(2) × 6(5)

= 5 + ( 5 × 5 × 5 ) - 6(2) × 6(5)

= 5 + ( 25 × 5 ) - 6(2) × 6(5)

= 5 + 125 - 6(2) × 6(5)

= 5 + 125 - ( 6 × 2 ) × 6(5)

= 5 + 125 - 12 × 6(5)

= 5 + 125 - 12 × ( 6 × 5 )

= 5 + 125 - 12 × 30

= 5 + 125 - ( 12 × 30 )

= 5 + 125 - 360

= 130 - 360
