100 eighths

the fraction with numerator 4th root of 200 and denominator 2
D
the fraction with numerator 4th root of 20 and denominator 2

Explanation

Rewrite the square root as a fourth root: √10 = ⁴√100. Then √10 ÷ ⁴√8 = ⁴√(100/8) = ⁴√(12.5). Choice D is equivalent because ⁴√200 ÷ 2 = ⁴√200 ÷ ⁴√16 = ⁴√(200/16) = ⁴√(12.5).
