I need help plz, i dont understand :(
dedylja [7]

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}

=answer A
