    Step-by-step explanation:

    “must be used first” is a very hard phrasing. multiplication is commutative.

    and I am not sure that the problem is stated correctly.

    I read here

    (i×y²) to the power of 1/3.

    i is the imaginary constant sqrt(-1) ?

    exponents brought themselves to the power of something else multiply.

    e.g.

    ({2}^{3})^{4}  =  {2}^{12}

    exponents in multimedia expressions of the same base simply add up.

    e.g.

     {2}^{3}  \times  {2}^{4}  =  {2}^{7}

    a negative exponent means that the expression with the same positive exponent is just at the bottom of a division.

    e.g.

     {2}^{ - 3}  = 1 \div  {2}^{3}

    and a fraction as exponent specifies a root to be taken.

    e.g

     {2}^{1 \div 3}  =  \sqrt[3]{2}

    so, I would do all the exponent multiplications to simplify the expression.

     \sqrt[3]{i \times  {y}^{2} }  =  ({i \times  {y}^{2} })^{1 \div 3}  =

     = ( { - 1}^{1 \div 2}  \times  {y}^{2} ) ^{1 \div 3}

    1/2 × 1/3 = 1/6

    2 × 1/3 = 2/3

     =  { - 1}^{1 \div 6}  \times  {y}^{2 \div 3}  =  \sqrt[6]{ - 1}  \times  \sqrt[3]{ {y}^{2} }

    so, as we can see, we can move freely from multiplying the fraction exponents to converting them into root expressions and vice versa.
