(15:3+2)³–(40:2–16)³
tolong pakai contoh![]()
tolong pakai contoh
(15 ÷ 3 + 2)³ - (40 ÷ 2 - 16)³
= (5 + 2)³ - (20 - 16)³
= 7³ - 4³
= (7 × 7 × 7) - (4 × 4 × 4)
= 343 - 64
= 279
Penjelasan dengan langkah-langkah:
[tex] \sf \: (15 \div 3 + 2 {)}^{3} - (40 \div 2 - 16 {)}^{3} [/tex]
[tex] \sf \: = (5 + 2 {)}^{3} - (20 - 16 {)}^{3} [/tex]
[tex] \sf \: = (7 {)}^{3} - (4 {)}^{3} [/tex]
[tex] \sf \: = (7 \times 7 \times 7) - (4 \times 4 \times 4)[/tex]
[tex] \sf \: = (49 \times 7) - (16 \times 4)[/tex]
[tex] \sf \: = 343 - 64[/tex]
[tex] \sf \: = \underline{ \boxed{ \red{ \sf \: 279}}}[/tex]
