Jawab:
a. 445
Penjelasan dengan langkah-langkah:
[tex]\sqrt[3]{6.859}[/tex] = 19 × 19 × 19
[tex]\sqrt[3]{6.859}[/tex] = [tex]\sqrt[3]{19^{3} }[/tex]
= 19
jadi, [tex]\sqrt[3]{6.859}[/tex] = 19
[tex]\sqrt{676}[/tex] = [tex]2^{2}[/tex] × [tex]13^{2}[/tex]
= 2 × 13
= 26
[tex]7^{2}[/tex] = 7 × 7
= 49
jadi, 19 × 26 - 49 = 445 ( A )
semoga membantu
