A nice beginning to 2021: this answer led me to some new-to-me math, to a new appreciation of sage/sympy, and to gratitude for this forum. Thanks--and happy new year!

sage: reset() sage: var('a b c x y z') (a, b, c, x, y, z)

sage: assert( (e^x)^y == e^(x*y) )

AssertionError Traceback (most recent call last) /Users/marks/mysage/sage-9.0/local/lib/python3.7/site-packages/sage/all_cmdline.py in <module>() ----> 1 assert( (ex)y == e*(xy) )

AssertionError: sage: assert( (e^2)^3 == e^(2*3) ) sage:

Is this a bug ?

sage: var('a b c x y z')
(a, b, c, x, y, z)
sage: assert( (e^x)^y == e^(x*y) )

Sagemath 8.8 won't run on MacOS 10.15 because of security locks. The system objects to software packages from "unknown" sources, like python and sage. It's possible to instruct the system to accept a package, but I've been able to do that only manually, one package at a time--a boring job withe sagemath's hundreds (?) of packages.

Help? Hints? Thanks!
