Answer:
Option (4)
Step-by-step explanation:
Let x = [tex]\sqrt[4]{7}[/tex]
[tex]\sqrt[4]{7}\times \sqrt[4]{7}\times \sqrt[4]{7}\times \sqrt[4]{7}[/tex] = (x)(x)(x)(x)
= [tex]x^{1+1+1+1}[/tex]
= x⁴
Now we substitute the value x = [tex]\sqrt[4]{7}[/tex]
x⁴ = [tex](\sqrt[4]{7})^4[/tex]
x⁴ = 7
Therefore, Option (4) will be the answer.
