Question 1057476
.
<pre>
1.  If A is a real number and you are seeking for the solutions in real numbers then


    A^4+2=11  --->  A^4 = 11-2  --->  A^4 = 9  --->  A^2 = {{{sqrt(9)}}}  --->  A^2 = 3  --->  A = +/- {{{sqrt(3)}}}.  

    Two solutions.



2.  If A is a complex number and you are seeking for the solutions in complex numbers then


    A^4+2=11  --->  A^4 = 11-2  --->  A^4 = 9  --->  A^2 = +/- {{{sqrt(9)}}}  --->  A^2 = +/- 3  --->  A = {{{sqrt(3)}}},  or A = {{{-sqrt(3)}}},  or A = {{{sqrt(3)*i}}},  or A = {{{-sqrt(3)*i}}}.  

    Four solutions.
