Answer:
A. 4xy [tex]\sqrt[4]{3y}[/tex]
Step-by-step explanation:
4√768x⁸y⁵
---> factor 768 --> 4x4x4x4x3
---> x⁸ = x⁴⁺⁴ = x⁴ . x⁴
---> y⁵ = y⁴⁺¹ = y⁴ . y¹
4√4⁴x3 x⁴ . x⁴ . y⁴ .y
since is 4th root, all the numbers with power to 4 comes out of the root
4x.x.y[tex]\sqrt[4]{3y}[/tex]
4x²y[tex]\sqrt[4]{3y}[/tex]
