Answer:
See below
Step-by-step explanation:
If an expression is not dependent on x, it simplified form must not contain x. To show that this is the case for (a) and (b) we need to simplify them and assess:
(a)
Indeed, does not depend on x!
And (b)
Again, does not depend on x.
The equivalent expression is . Option B
<h3>How to determine the expression</h3>
Given the expression
=
Divide the multipliers, we have
=
Let factorize the numerator in square root
=
Eliminate the like factor in both the numerator and denominator
=
Let's bring forth the 'x' factor, we have
=
Thus, the equivalent expression . Option B
