Soal !!
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

• 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
