Answer:

x^{-12}y^{2}z^{4}

Step-by-step explanation:

We have to simplify the given expression given as

[(x^{2}y^{3})^{-1}.(x^{-2}y^{2}z)^{2}]^{2}

[x^{-2}.y^{-3}.x^{-4}.y^{4}.z^{2}]^{2}

[x^{-2-4}.y^{-3+4}.z^{2}]^{2}=[x^{-6}.y^{1}.z^{2}]^{2}=x^{(-6-6)}.y^{1+1}.z^{2+2}=x^{-12}y^{2}z^{4}

Therefore simplification of the given expression gives x^{-12}y^{2}z^{4}

PLEASE HELP ME WITH THIS AND EXPLAIN :)
PSYCHO15rus [73]
So first, you need to find the y intercept and slope of the line/function.
then, you just plug it in to y=mx+b form
this one would be:
slope of -5/4
y intercept: 2
so it would be y=-5/4+2
