b) (0,8)⁴ : (2⅔)⁴

c) (-6,5)³/(-0,13)³

d) (4½)³ razy (-⅔)³ razy (-2)³

e) (2½)⁴ razy 0,6⁴ razy (-1/15)⁴

f) 0,3⁴ razy (2⅔)⁴ /(-4)⁴

Answer 1

a) (1 3/4)⁶ · (2/7)⁶ = (7/4)⁶ · (2/7)⁶ = (7/4 · 2/7)⁶ = (1/2)⁶ = 1/64

b) (0,8)⁴ : (2⅔)⁴ = (8/10)⁴ : (8/3)⁴ = (4/5 : 8/3)⁴ = (4/5 · 3/8)⁴ = (3/10)⁴ = 81/10000

c) (-6,5)³/(-0,13)³ = (-6,5 : -0,13)³ = 50³= 125000

d) (4½)³ · (-⅔)³ · (-2)³ = (9/2)³ · (-2/3)³ · (-2)³ = (9/2 · -2/3 · -2)³ = 6³ = 216

e) (2½)⁴ · 0,6⁴ · (-1/15)⁴ = (5/2)⁴ · (6/10)⁴ · (-1/15)⁴ = (5/2 · 3/5 · (-1/15))⁴ = (1/10)⁴ = 1/10000

f) 0,3⁴ · (2⅔)⁴ /(-4)⁴ = (3/10)⁴ · (8/3)⁴ : (-4)⁴ = (3/10 · 8/3)⁴ : (-4)⁴ = (4/5)⁴ : (-4)⁴ = (4/5 : -4)⁴ = (1/5)⁴ = 1/625
