On the number of integers which form perfect powers in the way of $ x(y_1^2+y_2^2+y_3^2+y_4^2) = z^k $

<p>Let $ k \geqslant 2 $ be an integer. We studied the number of integers which form perfect $ k $-th powers in the way of</p> <p class="disp_formula">$ x(y_1^2+y_2^2+y_3^2+y_4^2) = z^k. $</p> <p>For $ k \geqslant4 $, we established a unified asymptoti...
