Reduce a certain kind of multiplication expression and square root expression

Multiplication by a division expression. x * (y / z) can be better expressed as (x*y) / z. But before returning this new expression, reduce it by calling the reduce function on it. Reduce it after you create it but before you return it.

I have to make a function that can do this but can't seem to figure it out. So far I have this within a function:

elseif strcmp(Operand2{2}, 'Div')

    reduce(Operand2);
    Result = {'Num', Operand1{2} * Operand2{2}};

I also need a part of a function that can do this, "Radical is a power, and the exponentof that power is a number >= 2: Create a new 'Pow' expression using the same base but with an exponent that has had 2 subtracted from it. Reduce this expression and return it." So far I have this within a separate function.

if strcmp(radical{1},'Pow')

    reduce(radical);
    Result = reduce(sqrt(radical{2}));
