PLEASE HELP ASAP!!! CORRECT ANSWER ONLY PLEASE!!!

Which expression is equal to 5 /13√

?

Answer 1

`(5)/(√(13))\cdot(√(13))/(√(13))=(5√(13))/(13)`

`\text{Used:}\ √(a)\cdot√(a)=a`

Answer 2

5√13 / 13

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
