Which expression is equal to 5/13√ ?

[tex]\dfrac{5}{\sqrt{13}}\cdot\dfrac{\sqrt{13}}{\sqrt{13}}=\dfrac{5\sqrt{13}}{13}[/tex]
[tex]\text{Used:}\ \sqrt{a}\cdot\sqrt{a}=a[/tex]
Answer:
5√13 / 13
Step-by-step explanation:
If we have the expression:
5 / √13
We can only change the way it is expressed by multiplying it by 1 to not change the value and we know that1 is the same as a number divided by the same number:
In this case, we are going to multiply the expression by √13 / √13 which is equal to 1:
(5 / √13) * (√13 / √13)
Solving we get:
5*√13 / √13*√13
5*√13 / √13²
5*√13 / 13
