9x² + √x + x³ + 12 - x = ..x = 4

9x² + √x + x³ + 12 – x = ..x = 4

Jawaban:

218

Penjelasan dengan langkah-langkah:

$sf lim limits_{x to 4} (9 {x}^{2} + sqrt{x} + {x}^{3} + 12 - x) =$

$sf = 9 {(4)}^{2} + sqrt{4} + {4}^{3} + 12 - 4$

$sf = 9(16) + sqrt{ {2}^{2} } + (4 times 4 times 4) + 12 - 4$

$sf = 144 + 2 + 64 + 12 - 4$

$sf = 146 + 64 + 12 - 4$

$sf = 210 + 12 - 4$

$sf = 222 - 4$

$sf = 218$

Penjelasan dengan langkah-langkah:

9x² + √x + x³ + 12 – x

x = 4

_____

9(4²) + √4 + 4³ + 12 – 4

= 9(4 × 4) + √2² + (4 × 4 × 4) + 12 – 4

= 9(16) + 2 + (16 × 4) + 12 – 4

= 144 + 2 + 64 + 12 – 4

= 146 + 64 + 12 – 4

= 210 + 12 – 4

= 222 – 4

= 218
