Final answer:
The function f(x) = 5x²/(x-3) can be rewritten through algebraic manipulation, such as long division, but the question lacks sufficient context for a detailed step-by-step process.
Step-by-step explanation:
The function f(x) = 5x²/(x-3) can indeed be rewritten into a different form through algebraic manipulation. One such method involves dividing each term in the numerator by the denominator to simplify the expression. However, the portions of the question that mention re-expressing in fractional power or value of x not less than 5% of 0.50 do not directly relate to reformulating the function.
Moreover, completing the square would typically be more relevant to solving quadratic equations or rewriting quadratic functions in vertex form, which differs from this function's form. Also, the mention of drawing the graph of a function within an interval or the product of functions equating to a constant seems unrelated to the initial question.
The original question may be asking for long division or polynomial division to be used to simplify the function into a form where the remainder is written over the original divisor. Yet, due to the fragmented and disjointed additional information, there's not enough context given to provide a specific step-by-step process for rewriting the function in the form suggested.
