note : sertakan cara
Penjelasan dengan langkah-langkah:
[tex] \sf\sqrt[3]{125} + \sqrt[3]{27} \times {2}^{3} = [/tex]
[tex] \sf \to \sqrt{ {5}^{3} } + \sqrt{ {3}^{3} } \times (2 \times 2 \times 2)[/tex]
[tex] \sf \to5 + 3 \times (4 \times 2)[/tex]
[tex] \to \sf5 +(3 \times 8)[/tex]
[tex] \to \sf5 + 24[/tex]
[tex] \to \sf29[/tex]
Jawaban:
³√125 + ³√27 × 2³
= √5³ + √3³ × 2³
= ( 5 × 5 × 5 ) + ( 3 × 3 × 3 ) × ( 2 × 2 × 2 )
= ( 25 × 5 ) + ( 9 × 3 ) × ( 4 × 2 )
= 125 + 27 × 8
= 152 × 8
= 1.216
