⁴√28 ÷ ³√7
= (28)^¼ / (7)^⅓
= (7×4)^¼ / 7^⅓
= 7^¼ × 4¼ / 7^⅓
= 7^¼-⅓ × 4^¼
= 7^3-4/12 × 4^¼
= 7^-1/12 × 4^¼
= 4^¼/7^1/12
= ⁴√4/¹²√7
so your answer is ⁴√4/¹²√7
= (28)^¼ / (7)^⅓
= (7×4)^¼ / 7^⅓
= 7^¼ × 4¼ / 7^⅓
= 7^¼-⅓ × 4^¼
= 7^3-4/12 × 4^¼
= 7^-1/12 × 4^¼
= 4^¼/7^1/12
= ⁴√4/¹²√7
so your answer is ⁴√4/¹²√7
