# Question #95e73

##### 2 Answers

#### Explanation:

First find out what

So, we now know that the expression is now

Then, we rationalize the denominator as we cannot have a root as

the denominator:

Multiply both the numerator and the denominator by

Denominator

Numerator

Hence,

The expression is equivalent to

#### Explanation:

The square of

Therefore,

#sqrt(1/4 + 1/4)#

#sqrt(2/4)#

#sqrt(1/2)#

We can separate the radicals.

#sqrt(1)/sqrt(2)#

#1/sqrt(2)#

I would recommend you rationalize the denominators.

#1/sqrt(2) * sqrt(2)/sqrt(2)#

#sqrt(2)/2#

Hopefully this helps!
