### Can the square root of x be added to the square root of 3x?

No. The Square root of x is not the value of x. So it can not be
simplified beyond:
Root X + root 3x
Yes.
The square root of 3x equals the square root of 3 times the
square root of x, so when you add another square root of x, you can
factor out the square root of x, thereby simplifying the expression
to the square root of x times the sum of one plus the square root
of three.
