A. 7²/8²=49/64
b. 3³/4³+2³/3³= (3³.3³+2³4³)/(3³.4³) = (3^6+2^9)/12³ = 1242/1728
c. (-3/5)^5:(-3/5)² = (-3/5)^(5-2) =(-3/5)³ = -27/125
d. 5/8^(2×2)=(5/8)⁴=5⁴/8⁴=625/4096
e. ⅔^(3+2)=⅔^5=2^5/3^5= 32/243

A)(7/8)²=
7²/8² = 49/64
B)(3/4)³+(2/3)³=
= 27/64 + 8/27
= (27²+64×8)/(64×27)
= (729+512)/1.728
= 1.241/1.728
C)(-3/5)pangkat5:(-3/5)²
= (-3/5)^(5-2)
= (-3/5)³
= -27/125
D)((5/8)²)²
= (5/8)^(2×2)
= (5/8)⁴
= 625/2.048
E)(2/3)³×(2/3)²=
= (2/3)^(3+2)
= (2/3)^5
= 32/243
