Question

Subtracting Radicals
Combine the radicals gvx-37x.
5rx
–6/2x
-6

Answer 1

Given:

The expression is

`9√(x)-3√(x)`

To find:

The result after subtracting the radicals.

Solution:

We have,

`9√(x)-3√(x)`

We need to combine these terms.

Taking out common factors, we get

`=(9-3)√(x)`

`=6√(x)`

The result after subtracting the radicals is
`6√(x)`.

Therefore, the correct option is B.
