Prethanks to whoever uses some of their time to answer my question I have problem 7x to the zero power I am to understand the answer is 1 even though this would appear to go against the order of operations? That I should still look at it as anything to the zero power is 1? And.. if the answer were to be 7 then the problem would instead be (7)x to the zero power? Thank you, David

$$(7x)^0=1,\quad x\ne0$$$$7x^0=7,\quad x\ne0$$ Any real number, excluding zero, is 1 when raised to the zero power.

$$\left. \begin{align*}(7x)^0 = 7^0x^0 &= 1 \\ 7x^0 &= 7\end{align*} \right\rbrace (x \ne 0)$$ Anything (except zero) to the zeroth power is indeed one. Last edited by v8archie; December 8th, 2014 at 09:10 PM.
