Answer:
the last one is equal to the question....
Step-by-step explanation:
Answer:
(5√11)/11 (option 1)
Step-by-step explanation:
If you multiply both the top and bottom by √11, you will get 5√11/11.
Next, make sure that the other answers are wrong.
5=√25, so
√11*5=√11*√25
So option 2 and 3 are incorrect.
#4 is obviously wrong, as you cannot simply switch the square root symbol between the denominator and numerator.
