Подстановка условия
$$frac{1}{5} left(2 a^{frac{log{left (2 right )}}{log{left (b right )}}} + 3 b^{frac{log{left (2 right )}}{log{left (a right )}}}right)$$
(2*(-3/2)^(log(2)/log(b)) + 3*b^(log(2)/log((-3/2))))/5
$$frac{1}{5} left(2 (-3/2)^{frac{log{left (2 right )}}{log{left (b right )}}} + 3 b^{frac{log{left (2 right )}}{log{left ((-3/2) right )}}}right)$$
(2*(-3/2)^(log(2)/log(b)) + 3*b^(log(2)/log(-3/2)))/5
$$frac{1}{5} left(2 left(- frac{3}{2}right)^{frac{log{left (2 right )}}{log{left (b right )}}} + 3 b^{frac{log{left (2 right )}}{log{left (- frac{3}{2} right )}}}right)$$
2*(-3/2)^(log(2)/log(b))/5 + 3*b^(log(2)/(-log(2) + pi*i + log(3)))/5
$$frac{2}{5} left(- frac{3}{2}right)^{frac{log{left (2 right )}}{log{left (b right )}}} + frac{3}{5} b^{frac{log{left (2 right )}}{- log{left (2 right )} + log{left (3 right )} + i pi}}$$
