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/ $y^{2}$ * $z^{6}$

Mathematics

NO = 4.5

MO = 3.5

LN = sqrt(44)

Step-by-step explanation:

Since the value of the base of the triangles is 8, and the value of NO is 4.5, the value of MO is MN - NO, which is 8 - 4.5, which comes out to 3.5.

Then, we apply the quadratic formula to triangle MLO to find that the middle line value is sqrt(23.75). Then we use the quadratic formula on traingle OLN to find the LN is sqrt(44).
