Answer 2

Diketahui

Lim 6x + 3x³ - x¹

Ditanya

x → 9

Jawab :

= 6x + 3x³ - x¹

= 6(9) + 3(9)³ - 9¹

= ( 6 × 9 ) + 3(9³) - 9¹

= 54 + 3( 9 × 9 × 9 ) - 9¹

= 54 + 3( 81 × 9 ) - 9¹

= 54 + 3(729) - 9¹

= 54 + ( 3 × 729 ) - 9¹

= 54 + 2.187 - 9¹

= 54 + 2.187 - 9

= ( 54 + 2.187 ) - 9

= 2.241 - 9

= 2.232

Kesimpulan

Jadi, hasil nya adalah 2.232
