Answer:
The value of 
Step-by-step explanation:
We have given 
d=1.7
We have to find 
So,
from the formula

When n=14




Using the formula:

When n=26
![s_{26}=\frac{26}{2}[2(-18)+(26-1)(1.7)]](https://tex.z-dn.net/?f=s_%7B26%7D%3D%5Cfrac%7B26%7D%7B2%7D%5B2%28-18%29%2B%2826-1%29%281.7%29%5D)
On simplification we get:

Answer:
y^ ⁻⁹/⁴ * z^⁽⁻³⁾
Step-by-step explanation:
(Y^3 z^4)^(-3/4) = (y^3)^(-3/4) * (z^4)^(-3/4)
= y^3* ⁽⁻³/⁴⁾ * z^4 *⁽⁻³/⁴⁾
=y^ ⁻⁹/⁴ * z^⁽⁻³⁾
