Question

Wyznacz liczbę a:

a)

b)

Answer 1

a)

2√3 = ⁴√a

⁴√a = √(4*3)

⁴√a = √12

a^(1/4) = 12^(1/2)

[ a^(1/2) ]^(1/2) = 12^(1/2)

a^(1/2) = 12

 √a = 12    /²

a = 12²

a = 144

 

b)

⁴√a = √(9*2)

⁴√a = √18

a^(1/4) = 18^(1/2)

[ a^(1/2) ]^(1/2) = 18^(1/2)

a^(1/2) = 18

 √a = 18    /²

a = 18²

a = 324
