same formula two diff results? - OneRanger - 09-08-2021 02:42 AM In the attached image, you see the same formula twice differing only by putting ()'s around the negative number to which the exponent is applied. Is there something I should know here? I can see how this could really bite someone in the backside.

See the Prime's Algebraic precedence in the following post. https://www.hpmuseum.org/forum/thread-17416-post-151645.html#pid151645 |
