Odpowiedź:
wraz z sposobem rozwiązania
Szczegółowe wyjaśnienie:
c) 3^3/2 : 3^1/2 = 3^3/2 - 1/2= 3^1 = 3
d) (5^2 * 5^1/2) : 5^3/2 = 5^2 + 1/2 - 3/2 = 5^1 = 5
e) 15^1/2 * 0,36^1/4 = 15^1/2 * ([tex]\frac{9}{25}[/tex])^1/4 = [tex]\frac{15^1/2 * (3^{2})^1/4 }{(5^{2})^1/4 }[/tex] = [tex]\frac{15^1/2 * 3^1/2}{5^1/2}[/tex] =
(15 * 3)^1/2 : [tex]\sqrt{5}[/tex] = [tex]\frac{\sqrt{45} }{\sqrt{5} }[/tex] = [tex]\sqrt{9}[/tex] = 3
f) 20^1/3 * 2,5^-1/3 = 20^1/3 * ([tex]\frac{1}{2,5}[/tex])^1/3 = (20 * [tex]\frac{2}{5}[/tex])^1/3 = (4 * 2)^1/3 = 8^1/3 =
(2³)^1/3 = 2
