You can put this solution on YOUR website! 2 {sqrt x^3} + 5x{sqrt x} - 3{sqrt x^5}
You can rewrite as:
2 {sqrt x*x*x} + 5x{sqrt x} - 3{sqrt x*x*x*x*x}
Now, you can "pull out" pairs:
2x {sqrt x} + 5x{sqrt x} - 3x^2{sqrt x}
Factor out the sqrt x:
{sqrt x}[2x + 5x - 3x^2]
Combine like-terms:
{sqrt x}[7x - 3x^2]
Pull out the 'x':
x{sqrt x}[7-3x]
