Question 1143859
A) 3
Let {{{ x = 0 }}}
{{{ ( x-1 )^4 = 1 }}}
{{{ ( 0-1 )^4 = 1 }}}
{{{ -1 }}} raised to an even power  = {{{ 1 }}}
and
{{{ x + 3 = 0 + 3 }}}
-------------------------
The other solution is:
{{{ ( 2 - 1 )^4 = 1 }}}
{{{ 1^4 = 1 }}}
but
{{{ 2 + 3 = 5 }}} which is not one of the choices
