Rationalize, what? All you can do is simplify numerator and denominator.

%284%2A2%2At%2At%2Ahrb%29%2F%284%2A125%2At%2At%2Ahr%2Aa%5E9%29

%288hrbt%5E2%29%2F%284%2A125hrt%5E2%2Aa%5E9%29

%282hrt%5E2b%29%2F%28125hrt%5E2%2Aa%5E9%29

%282b%29%2F125a%5E9%29

Saw your note:
You really want for root%284%2C2b%29%2Froot%284%2C125a%5E9%29, and to simplify this.

Multiply the entire expression by %28root%284%2C125a%5E9%29%2Froot%284%2C125a%5E9%29%29%5E3.
