Hello. Please refrain from changing the power rule: you have been doing so incorrectly. The power can be any real number: there is no requirement that it be an integer or natural number. Sometimes, in calculus texts it is introduced this way at first, but later in the text the full power rule is shown to not require the exponent be an integer. Thanks.

Hi Manulinho72. You tagged this image as incorrect in the PAH article. You may want to tag the image also directly on Commons using c:Template:Disputed chem (giving further details) or to nominate it for deletion. --Leyo 07:37, 30 October 2014 (UTC)[reply]

Hi Leyo, Thanks for the comment I am really really busy rightnow. It is simple, the molecule of the image is not Zethrene, could you do that?
