Answer:
[tex]y^{\frac{3}{7}}[/tex]
Step-by-step explanation:
[tex]\sqrt[7]{y^3}=y^{\frac{3}{7}}[/tex]
The root of the radical will become the denominator of the exponent fraction and the power of the radical will become the numerator of the exponent fraction
7 ---> is the root of the radical
3 is the power of the radical
