Odpowiedź:
a)
16^-1/2 + 25^-1/2 = √1/16 + √1/25 = 1/4 + 1/5 = 5/20 + 4/20 = 9/20
b)
27^2/3 + (9/16)^-1/2 = ∛27² + √16/9 = (∛27)² + 4/3 = 3² + 1 1/3 = 9 + 1 1/3 = 10 1/3
c)
(9/11)^1/2 * 11^1/2 = (9/11 * 11)^1/2 = √9 = 3
d)
25^3/4 : 25^1/4 = (25³ : 25)^1/4 = ∜25² = √25 = 5
e)
100^0,1 : 100^0,6 = 100^-0,5 = 100^-1/2 = √1/100 = 1/10
