Question 775469
<pre>
If it's
 
(-5)<sup>4</sup> , with the negative sign inside parentheses, 

then it means (-5)(-5)(-5)(-5) = +625

But if it's

-5<sup>4</sup> ,  with the negative sign NOT inside parentheses,

 then it means -1×(5)(5)(5)(5) = -625

Always be sure which it is, so you won't get the sign wrong.
