a) (½)²⁰⁰¹ · 2²⁰⁰¹ =(½*2)²⁰⁰¹=1²⁰⁰¹=1
b) (⅕)⁶ · 5⁶ · 10⁶ =(⅕*5*10)⁶=10⁶= 1 000 000
c) 0,25⁴ · 4⁴ · 10 ⁴ =(0,25*4*10)⁴=10⁴= 10 000
2. oblicz wartość wyrażenia
a) (⅖)⁵ · (¾)⁵ =(⅖ * ¾)⁵=(3/10)⁵=243/100000
b) (½)⁴ · (⅔)⁴ =(½ * ⅔)⁴ = (2/6)⁴= (⅓)⁴=1/81
c) (1½)⁵⁰ · (⅖)⁵⁰ = (3/2*⅖) ⁵⁰=(⅗)⁵⁰
a) (½)²⁰⁰¹ · 2²⁰⁰¹ = 1 ²⁰⁰¹ = 1
b) (⅕)⁶ · 5⁶ · 10⁶ = 10⁶ = 1000000
c) 0,25⁴ · 4⁴ · 10⁴= 10⁴ = 10000
2.
a) (⅖)⁵ · (¾)⁵ = (1/5)⁵· (3/2)⁵ = (3/10) <do potęgi piątej>
b) (½)⁴ · (⅔)4 = (1/3) do potęgi 4
c) (1½)⁵⁰ · (⅖)⁵⁰ = (3/5) do potęgi 50
