Answer:

[tex]7[/tex]

Step-by-step explanation:

we have

[tex]\sqrt[4]{7} *\sqrt[4]{7} *\sqrt[4]{7} *\sqrt[4]{7}[/tex]

we know that

[tex]\sqrt[4]{7} *\sqrt[4]{7} *\sqrt[4]{7} *\sqrt[4]{7}=(\sqrt[4]{7})^{4}[/tex]

[tex](\sqrt[4]{7})^{4} =(7^{\frac{1}{4}})^{4}[/tex]

[tex](7^{\frac{1}{4}})^{4}= (7^{\frac{4}{4}})[/tex]

[tex](7^{\frac{4}{4}}) =7[/tex]
