Question 16346
 Any non-zero number raised to the zero power is 1.  So x^0=1, y^0=1, (3x)^0 =1, (Junk)^0 = 1.


However, in the case of 3x^0 where there are no parentheses, ONLY the x is raised to the zero power.  So what you have is 3 times x^0, which is 3* 1=3.


So, in answer to your question:
{{{3x^0 +(3x)^0}}}
{{{ 3*1 + 1}}}
{{{3+1}}}
{{{4}}}
