Jawaban:
1. 16 × 2 = 32
2. 16 × 3 = 48
3. 16 × 4 = 64
4. 15 × 5 = 75
Karena mengalikan bilangan yg sama dan berulang maka tinggal dikalikan saja.
Semoga membantu... ^_^
Jawaban:
1. 2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2= 32 / 16 × 2 = 32
2. 3+3+3+3+3+3+3+3+3+3+3+3+3+3+3+3= 48 / 16 × 3 = 48
3. 4+4+4+4+4+4+4+4+4+4+4+4+4+4+4+4= 64 / 16 × 4 = 64

18. urutkan bilangan 3^4(tiga pangkat empat),4^3, 2^5, 5^2 dari yang terkecil ke yang terbesar a.3^4 , 4^3 , 2^5 , 5^2b.5^2 , 2^5 , 4^3 , 3^4c.5^2 , 2^5 , 3^4 , 4^3d.5^2 , 4^3 , 2^5 , 3^4
Jawabannya adalah :
3^4 , 4^3 , 2^5 , 5^2
=81 , 64 , 32 , 25
=5^2 , 2^5 , 4^3 , 3^4
b.5^2 , 2^5 , 4^3 , 3^4
terimakasih semoga bermanfaat
19. 1.) 5√2+√3-4√2=2.) 7√3+4√5-3√3+√5=3.) 5×(2√3-√2)= 4.) 4√2×(3√3-√2) =5.) (3+5√2) (2√2-3√3) =6.) (2√3-4) (√5-3√2) =tolong di jawab ya
1)
[tex]5 \sqrt{2} + \sqrt{3} - 4 \sqrt{2} = \sqrt{2} + \sqrt{3} [/tex]
2)
[tex]7 \sqrt{3} + 4 \sqrt{5} - 3 \sqrt{3} + \sqrt{5} = 4 \sqrt{3} + 5 \sqrt{5} [/tex]
3)
[tex]5 \times (2 \sqrt{3} - \sqrt{2} ) = 10 \sqrt{3} - 5 \sqrt{2} [/tex]
4)
[tex]4 \sqrt{2} \times (3 \sqrt{3} - \sqrt{2} ) = 12 \sqrt{6} - 4 \sqrt{4} = 12 \sqrt{6} - 6[/tex]
5)
[tex](3 + 5 \sqrt{2} )(2 \sqrt{2} - 3 \sqrt{3} )[/tex]
[tex](3 \times 2 \sqrt{2} ) + (3 \times ( - 3 \sqrt{3} )) + (5 \sqrt{2} \times 2 \sqrt{2} ) + (5 \sqrt{2} \times ( - 3 \sqrt{3} )[/tex]
[tex]6 \sqrt{2} + ( - 9 \sqrt{3} ) + 10 \sqrt{4} + ( - 15 \sqrt{6} )[/tex]
[tex]6 \sqrt{2} - 9 \sqrt{3} + 20 - 15 \sqrt{6} [/tex]
6)
[tex](2 \sqrt{3} - 4)( \sqrt{5} - 3 \sqrt{2} )[/tex]
[tex](2 \sqrt{3} \times \sqrt{5} ) + (2 \sqrt{3} \times ( - 3 \sqrt{2} ) + ( - 4 \times \sqrt{5} ) + ( - 4 \times ( - 3 \sqrt{2} )[/tex]
[tex]2 \sqrt{15} + ( - 6 \sqrt{6} ) + ( - 4 \sqrt{5} ) + 12 \sqrt{2} [/tex]
[tex]2 \sqrt{15} - 6 \sqrt{6} - 4 \sqrt{5} + 12 \sqrt{2} [/tex]
20. urutkan bilangan 3^4(tiga pangkat empat),4^3, 2^5, 5^2 dari yang terkecil ke yang terbesar a.3^4 , 4^3 , 2^5 , 5^2b.5^2 , 2^5 , 4^3 , 3^4c.5^2 , 2^5 , 3^4 , 4^3d.5^2 , 4^3 , 2^5 , 3^4
dari yang terkecil = 5^2,2^5,4^3,3^4
Penjelasan dengan langkah-langkah:
3^4=3×3×3×3 =81
4^3=4×4×4 =64
2^5=2×2×2×2×2 =32
5^2=5×5 =25
