√10²=10
√4¹⁰=√(4⁵)²=4⁵=1024
∛125²=∛(5³)²=∛(5²)³=5²=25
⁵√32³=⁵√(2³)⁵=8
⁸√625²=⁸√(5⁴)²=⁸√5⁸=5
√√81=⁴√81=3
∛√27²=⁶√(3³)²=⁶√(3²)³=⁶√3⁶=3
∛√4³=⁶√64=2

∛⁴√16⁶=¹²√(4²)⁶=¹²√4¹²=4
Oblicz:
a) (√10)² = 10
b) √4¹⁰ = 4^(10/2) = 4^5 = 1024
c) ∛125² = ∛125 * 125) = ∛125 * ∛125 = 5 * 5 = 25
d) ⁵√32³ = ⁵√(32 * 32 * 32) = ⁵√32 * ⁵√32 * ⁵√32 = 2 * 2 * 2 = 8
e) (⁸√625)² = ⁴√625 = ⁴√(5 * 5 * 5 * 5) = 5
f) √√81 = √9 = 3
g) (∛√27)² = (∛(27^1/2))²= (27^1/6)² = 27^1/3 = ∛27 = 3
h) ∛√4³ ∛(√(4 * 4 *4) = ∛(2 * 2 * 2) = 2
i)(√∛49)³ = (√(49^1/3))³ = (49^1/3 : 2)³ = (49^(1/6))³ = 49^(1/2) = √49 = 7
j) ∛⁴√16⁶ = ∛(⁴√(16 * 16 * 16 * 16 * 16 * 16) = ∛(2 * 2 * 2 * 2 * 2 * 2) = 2 * 2 = 4
