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!
