My calculator shows this as -1/c^12

Did I miss something

### Re: Graphing Parabola, negative x values

Hi Not sure what the plug - chug means This is what the book shows: A negative number with an exponent (exponentiation), will first have the exponent evaluated, and then have the opposite applied, ie. -2^2 = -4 However, if the negative number is enclosed with parentheses, (-2)^2, that indicates (-2)...

### Re: Finding unknown n th roots ?

Hi All, Ok I found the answer to my question by having it right in front of me and not realizing it. I just take the log of both sides of the equation, isolate the variable by division, which leaves me with 7.1584 = x/0.4191.Then I just solve for x. It took me a while to realize that it does not mat...
