Question

Which is equivalent to -4 sqrt of 9 1/2x

Answer 1

To solve this problem you can apply the proccedure shown below:
 1. You have the fexpression given in the problem above, which you can rewrite it as following:
 -4√(9/2x)
 2. You can find an equivalent expression:
 -4√(3²/2x)
 (-4)(3)√(1/2x)
 -12/√2x
 3- If you multiply the numerator and the denominator by √2, you obtain:
 (-12√2)/[(√2)²√x]
 (-12√2)/(2√x)
 (-6√2)/(√x)
 Therefore, the answer is:-(-6√2)/(√x)
