Answer:

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)
