<h2>Answer: <u> (-5x⁴)(√(4x + 7)) </u></h2><h2> 4x + 7</h2>

<h3>Step-by-step explanation:</h3>

The question is asking us to make the denominator a rational function by finding a way to remove the square root without changing the value of the overall function.

We can do this by multiplying the denominator and numerator by the √(4x + 7), since multiplying a root term by that root term = the number being rooted (√x × √x = x).

√(4x + 7) √(4x + 7) 4x + 7
