Yes it does in this case. X⁴ can = 20. Take the 4th root of 20 or find what to the fourth power is equal to 20 [tex] \sqrt[4]{20} = x [/tex] X is equal to 2.1147. And you can re-check. What is 2.1147⁴? It's 20! So thus x= 2.1147
[tex]{ x }^{ 4 }=20\\ \\ x=\pm \sqrt [ 4 ]{ 20 } [/tex]

Simpler explanation:

[tex]{ x }^{ 4 }=20\\ \\ x=\pm { 20 }^{ \frac { 1 }{ 4 } }[/tex]
