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!
