SOLUTION: How would I simplify this expression {{{expr(root(3,3)/x^"")*expr(root(3,9)/x^2)}}} This is what I have and I am not sure if this right. I multiplied both √3*√9=&#873

Question 945644: How would I simplify this expression expr%28root%283%2C3%29%2Fx%5E%22%22%29%2Aexpr%28root%283%2C9%29%2Fx%5E2%29
This is what I have and I am not sure if this right. I multiplied both √3*√9=√27 and x*x^2=x^2. My answer is 3x^2, am I right?

No, because x*x2 = x3, not squared,
and also it's in the denominator.  You did the root part right,
but botched the "x part".  

expr%28root%283%2C3%29%2Fx%5E%22%22%29%2Aexpr%28root%283%2C9%29%2Fx%5E2%29%22%22=%22%22

root%283%2C27%29%2Fx%5E3%22%22=%22%22

3%2Fx%5E3
