Substitute the x and y that were given

eviant:

y=2, x=-4

dude:

Also $$x^{-n}=\frac{1}{x^n}$$ n being any number Likewise $$\frac{1}{x^{-n}}=>x^n$$

Yes

$\frac{ 1 }{ 4 }$-$\frac{ 1 }{ 64 }$, 32

dude:

That is confusing to look at $$\large \frac{1}{2^{-2}x^{-3}y^5}$$, $$x=2, y=-4$$ $$\large \frac{1}{2^{-2}2^{-3}-4^5}$$ $$\large \frac{1}{\color{red}{2^{-2}2^{-3}}-4^5}$$ The red will flip to go on the numerator and will lose the - exponent

$\frac{ 1 }{ 4 }$,$\frac{ 1 }{ 8 }$,-1024

Also quick note, if you want to copy the latex, right-click the math and Show Math As > Tex Commands When pasting include  in between

@dude thanks how do I get the final answer

6 months ago
dude:

$$\large \frac{1}{2^{-2}2^{-3}-4^5}$$ After flipping the numbers to the numerator =$$\large \frac{2^{2}2^{3}}{-4^5}$$ $$2^2=4$$ $$2^3=8$$ and $$-4^5=-1024$$

dude:

$$\large \frac{4\cdot 8}{-1024}$$ =$$\large -\frac{32}{1024}=>\boxed{\frac{1}{32}}$$

@dude pardon but the result is minus 1/32

@ThisGirlPretty do you agree it ?

dude:

Right, thank you $$\large -{\frac{1}{32}}$$
