a)
√2 = 2^1/2
b)
∛2 = 2^1/3
c)
√0,5 = √1/2 = 2^-1/2
d)
∛4 = ∛2² = 2^2/3
e)
√512 = (2^9)^1/2 = 2^9/2
f)
∛1024 = (2^10)^1/3 = 3^10/3
g)
2√2 = 2 * 2^1/2 = 2^3/2
h)
2∛2 = 2 * 2^1/3 = 2^(3/3 + 1/3) = 2^4/3
2.
√7³ = 7^3/2
∛7² = 7^2/3
1/√7 = 7^-1/2
1/∛7 = 7^-1/3
√1/7³ = 7^-3/2
1/⁵√7³ = 7^-3/5
49√7 = 7² * 7^1/2 = 7^(2+1/2)
7 * ⁵√7 = 7^(1 + 1/5)
