Can we express $expBig(sum_ialpha_iln(x_i)Big) = sum_ialpha_iexpbig(ln(x_i)big)$? [closed]

Is this equality correct:
$$expBig(sum_ialpha_iln(x_i)Big) = sum_ialpha_iexpbig(ln(x_i)big),?$$



I need to express $prod_ix_i^alpha^i$ using exp and logarithm.



How can I do this if the aforementioned way is incorrect?

No, it is incorrect. Instead of the sum on the r.h.s, you need a product.



$$exp(sum_ialpha_iln x_i)=prod_ix_i^alpha_i$$
