Does the equation $a^{2} + b^{7} + c^{13} + d^{14} = e^{15}$ have a solution in positive integers
Given, $$a^{2} + b^{7} + c^{13} + d^{14} = e^{15}\tag1$$
Assume $a=4^{182x},\;b=4^{52x},\;c=4^{28x},\;d=4^{26x},\;e=4^{y}$. Substituting into $(1)$ we get, $$4^{364x+1}=4^{15y}\tag2$$
which is true if, $$364x+1=15y\tag3$$
The last equation has solutions of the form
$$x=11+15n\\y=267+364n$$
Thus the equation $(1)$ has infinitely many solutions, the simplest one using $n=0$,
$$(a,b,c,d,e)=(4^{2002},4^{572},4^{308},4^{286},4^{267})$$
Please be kind with my attempt at a solution, and let me know where I’ve gone wrong.
Using the method shown by @Aditya Narayan Sharma, $$a^{2} + b^{7} + c^{13} + d^{14} = e^{15}\tag1$$
Put $a=2^{91x},\;b=2^{26x},\;c=2^{14x},\;d=2^{13x},\;e=2^{y}$. Then (1) becomes, $$2^{182x}+2^{182x}+2^{182x}+2^{182x}=2^{15y}$$ $$4*2^{182x}=2^{15y}$$ $$2^{182x+2}=2^{15y}\tag2$$ So, $$182x+2=15y$$ $$182x-15y=-2\tag3$$ Giving, $$x=14+15n$$ $$y=170+182n$$
Using $n=0$,
$$(a,b,c,d,e)=(2^{1274},2^{364},2^{196},2^{182},2^{170})$$
