Jawaban dan Penjelasan

Berikut ini adalah pilihan jawaban terbaik dari pertanyaan diatas.

☁JAWABAN☁

\\

\\ \sqrt{625} - \sqrt[3]{343} \times \sqrt[3]{1.728}

\\ = \sqrt{(25 \times 25)} - \sqrt[3]{(7 \times 7 \times 7)} \times \sqrt[3]{1.728}

\\ = 25 - \sqrt[3]{(7 \times 7 \times 7)} \times \sqrt[3]{12 \times 12 \times 12}

\\ = 25 - (7 \times 12)

\\ = 25 - 84

\\ = - 59

\\ \\ \\

Lim x - 2 + 7x × 8!!!

x → 5

\\

= x - 2 + 7x × 8!!!

  • = 5 - 2 + 7(5) × 8!!!

  • = 5 - 2 + ( 7 + 7 + 7 + 7 + 7 ) × 8!!!

  • = 5 - 2 + ( 14 + 7 + 7 + 7) × ( 8 × 5 × 2 )

  • = 5 - 2 + ( 21 + 7 + 7 )× ( 40 × 2 )

  • = 5 - 2 + ( 28 + 7 ) × 80

  • = 5 - 2 + (35 × 80)

  • = 5 - 2 + 2.800

  • = 3 + 2.800

  • = 2.803
