Best ResponseYou've already chosen the best response.1You are using some wobbly notation. If I read it correctly, the second and fourth are close, but not actually equivalent. 1/x⁻¹ = x, for x ≠ 0 x^(1/3) · x^(1/3) · x^(1/3) = x^(1/3 + 1/3 + 1/3) = x¹ = x

Best ResponseYou've already chosen the best response.0this is what they look like \[4\sqrt[]{x^3}\] \[\frac{ 1 }{ x^1 }\] \[10\sqrt{x^5*x^4*x^2}\] \[x \frac{ 1 }{ 3 }*x \frac{ 1 }{ 3 }*x \frac{ 1 }{ 3 }\]

Best ResponseYou've already chosen the best response.0@Jacob902 so are none of them equivalent?
