Got no credit for writing a square root with index












0












$begingroup$


On a quiz, I was asked to rewrite an expression as a radical. I wrote the square root with a $2$ in the index, but I received no credit. Is it completely wrong to write the $2$ even though usually you don't?



Question: Rewrite $(5x)^{3/2}$ in radical form. I wrote $(sqrt[2]{5x})^3$.

    Maybe you missed the points because the rest of your answer is wrong? Without seeing what you’ve written or the original question, we cannot help at all. (Even seeing them, we can’t magically give your points back, either. It ultimately rests upon your TA or Professor).

    It's probable that the expected answer is $5xsqrt{5x}.$
