5 * sqrt(5) = 5^1 * 5^0.5 = 5^(1 + 0.5) = 5^1.5

5 x 5^(1/2) = 5^(3/2)

5^1.5=5*5^1/2=5√5

5√5
= 5*5^(1/2)
= 5^(3/2)
= 5^1.5
= 5*5^(1/2)
= 5^(3/2)
= 5^1.5

5 √5 = 5^n
=> 5 * 5^(1/2) = 5^n
=> 5^(1+1/2) = 5^n
=> n = 1 + 1/2 = 3/2
=> 5 * 5^(1/2) = 5^n
=> 5^(1+1/2) = 5^n
=> n = 1 + 1/2 = 3/2

5√5 = 5 * (5)^(1/2) = 5^(3/2)
n = (3/2) or 1.5
Σ
n = (3/2) or 1.5
