Question 894325
{{{a^2=5+b^2}}}
In these graphs, {{{y=a}}} and {{{x=b}}}
.
.

{{{drawing(300,300,-5,5,-5,5,grid(1),graph(300,300,-5,5,-5,5,sqrt(5+x^2)))}}}
.
.
.
{{{a^3=35-b^3}}}
{{{drawing(300,300,-5,5,-5,5,grid(1),circle(2,3,0.2),graph(300,300,-5,5,-5,5,sqrt(5+x^2),(35-x^3)^(1/3)))}}}
One solution occurs at {{{b=2}}} and {{{a=3}}}
.
.
.
{{{drawing(300,300,-7,2,-2,7,grid(1),circle(-4.39,4.93,0.2),graph(300,300,-7,2,-2,7,sqrt(5+x^2),(35-x^3)^(1/3)))}}}
The other solution is a little more difficult to pick out graphically.
{{{b=-4.39}}} and {{{a=4.93}}}.
