Question

I need help plz, i dont understand :(

Answer 1

Answer:

Step-by-step explanation:

follow a few exponent rules and you can figure this out

when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal   $x^{-2}$  is  1/$x^{2}$    soooo...

mutilply the  -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o

= $8^{-2/3}$$w^{-14/3}$$x^{10/3}$$y^{-6/3}$$z^{18/3}$

= 1/$\sqrt[3]{8*8}$ * 1/$w^{14/3}$ * $x^{10/3}$ * 1/$y^{2}$ * $z^{6}$

= 1/$\sqrt[3]{64}$* 1/$w^{14/3}$ *$x^{10/3}$ * 1/$y^{2}$ * $z^{6}$

= 1/4* 1/$w^{14/3}$ *$x^{10/3}$ * 1/$y^{2}$ * $z^{6}$
