Answer:
sqrt(13z)/sqrt(13z)
Step-by-step explanation:
The factor that will remove the square root from the denominator will have that same root in the denominator. Since you want its value to be 1, it will be ...
sqrt(13z)/sqrt(13z)
After you multiply by this factor, the expression with rationalized denominator is ...
[tex]\dfrac{1}{\sqrt{13z}}=\dfrac{1}{\sqrt{13z}}\cdot\dfrac{\sqrt{13z}}{\sqrt{13z}}=\dfrac{\sqrt{13z}}{13z}[/tex]
