Nay0823

Penjelasan dengan langkah-langkah:

Lim x² + 20x × 6!

x → 5

Penyelesaian:

Lim 5² + 20(5) × 6!

= (5 × 5) + (20 × 5) × (6 × 5 × 4 × 3 × 2)

= 25 + 100 × (30 × 4 × 3 × 2)

= 25 + 100 × (120 × 3 × 2)

= 25 + 100 × (360 × 2)

= 25 + 100 × 720

= 25 + (100 × 720)

= 25 + 72.000

= 72.025

Eutopya

Jawaban:

72.025

Penjelasan dengan langkah-langkah:

$\displaystyle\sf\lim_{x \to 5}~ {x}^{2} + 20x \times 6!$

$\displaystyle \sf \: \: \: \:= {5}^{2} + 20(5) \times ( \underline{6 \times 5} \times \underline{4 \times 3} \times \underline{2 \times 1})$

$\displaystyle \sf \: \: \: \:= (5 \times 5) + (20 \times 5)\times (30 \times 12 \times 2)$

$\displaystyle \sf \: \: \: \:= 25 +100\times (360\times 2)$

$\displaystyle \sf \: \: \: \:= 25 +100\times 720$

$\displaystyle \sf \: \: \: \:= 25 +72.000$

$\displaystyle \sf \: \: \: \:= 72.025$
