Penjelasan dengan langkah-langkah:

1. a = 3, b = -2

a³b + (ab)² – b³

= 3³.(-2) + (3.(-2))² – (-2)³

= 27.(-2) + (-6)² – (-8)

= -54 + 36 + 8

= -18 + 8

= -10

2. 4^3times4^-^5 = 4^3^+^(^-^5^)=4^-^2=frac{1}{4^2}=frac{1}{16}

3. (frac{2}{3})^8:(frac{2}{3})^5=(frac{2}{3})^8^-^5=(frac{2}{3})^3=(frac{2^3}{3^3})=frac{8}{27}
