-3^-2

OpenStudy (unklerhaukus):

\[-3^{-2}=-\frac{1}{3^2}\]

OpenStudy (unklerhaukus):

\[(-3)^{-2}=\frac{1}{(-3)^2}=\frac{1}{3^2}\]

OpenStudy (anonymous):

thanks, what about -3^0

OpenStudy (unklerhaukus):

\[-3^0=-1\] but \[(-3)^0=1\]

OpenStudy (anonymous):

so its a trick question? there are no parenthesis

OpenStudy (unklerhaukus):

do you think the - is ment to squared too?

OpenStudy (anonymous):

the actual question was solve for x= -3 x^-2 x^-1 x^0 x^1 x^2 i solved t he x^1 and x^2 myself

OpenStudy (unklerhaukus):

well all of x is being squared so the negative would get squared ...etc

OpenStudy (unklerhaukus):

when \[x=-3\]\[x^{-2}=(-3)^{-2}=\frac{1}{(-3)^2}\]

OpenStudy (unklerhaukus):

i hope you squared away the negative in x^2 when x=-3

OpenStudy (anonymous):

yes, -3^2=9

OpenStudy (unklerhaukus):

yeah but to avoid confusion is is better to write (-3)^2=9

OpenStudy (anonymous):

ok, thanks

\[\Huge{\color{red}{-3x^{-2}}}\]\[\LARGE{\color{green}{\implies \frac{1}{-3^2}^2}}\]\[\LARGE{\color{blue}{\implies x=\frac{1}{9}}}\]
