Penjelasan dengan langkah-langkah:
1.
a. 6×(-3) = -18
b. -9×(-3) = 27
c. -8×7 = -56
d. 4×11 = 44
no 2, 3 dan 5 takut salah jawab
4.
a. 20:(-5) = -4
b. -12:(-3) = 4
c. 32:4 = 8
d. -18:6 = -3
1. a. 6 × (-3) = -18
b. -9 × (-3) = -27
c. -8 × 7 = -56
d. 4 × 11 = 44
2. a. 5⁸ = 5 × 5 × 5 × 5 × 5 × 5 × 5 × 5
= 390.625
b. -10⁶ = -10 × (-10) × (-10) × (-10) × (-10) × (-10)
= 1.000.000
c. 2⁴ × 10⁷ = (2×2×2×2) × (10×10×10×10×10×10×10)
= 16 × 10.000.000
= 160.000.000
d. -2⁴ × (-3)⁵ = (-2×(-2)×(-2)×(-2)) × (-3×(-3)×(-3)×(-3)×(-3))
= 16 × (-243)
= 3.888
3. (4 detik : 2 detik) × 5 meter = 2 × 5 meter = 10 meter
Jadi, posisi penyelam tersebut sekarang adalah 10 meter
4. a. 20 : (-5) = -4
b. -12 : (-3) = 4
c. 32 : 4 = 8
d. -18 : 6 = -3
5. 3 jam = 3 × 60 menit = 180 menit
180 menit : 30 menit = 6
1/2⁶ = 1/2 × 1/2 × 1/2 × 1/2 × 1/2 × 1/2 = 3 liter
Jadi, kandungan cairan A dalam ramuan obat tersebur adalah 3 liter
semoga membantu^^
