a) 2⁷ x 5⁷ = 10^7 = 10000000
b) (½)⁵ x 4⁵ = 2^5 = 32
c) 16¹⁰ : 8¹⁰ = 2^10 = 1024
d) (⅗)⁴ : (⅕)⁴ = 3^4 = 81
e) 0,2³ x 10³ = 2^3 = 8
Zapisz w postaci jednej potęgi i oblicz.
a) 2⁷ x 5⁷= (2*5)⁷ = 10⁷
b) (½)⁵ x 4⁷ = (1/2*4)^(9) = 2⁹
c) 16¹⁰ : 8¹⁰= (16: 8)¹⁰ = 2¹⁰
d) (⅗)⁴ : (⅕)⁴=[ (3/5):(1/5)]⁴ = [(3/5)*5]⁴= 3⁴
e) 0,2³ x 10³ = (0,2*10)³ = 5³
