Question

PLEASE HELP!!!!!!
Which expression is equal to 511√

Answer 1

`(5√(11) )/(11)`

Explanation:

To cancel out a square-rooted number at the denominator, we can multiply the square-rooted number by multiplying the square root number over again:

`(5)/(√(11))` *
`(√(11))/(√(11))`

Now, any same number of square root times another same number of a square root will cancel out the root. So
`√(11)` *
`√(11)` will equal 11.

With this information, we can now go back to the problem, so we will get:

`(5√(11))/(11)`
