Chapter 14.3, Problem 8SC

Explanation of Solution

Size of the value n:

It is given that value obtained for $\frac{\text{1}}{\text{2}}{\text{n}}^2$ should be bigger than $\frac{\text{5}}{\text{2}}\text{n-3}$.

Substituting the values of n,

If the value of n is 4 then

Substituting the values of n, $\frac{\text{5}}{\text{2}}\text{n-3}$

$\begin{array}{l}\frac{\text{5}}{\text{2}}\text{n-3}\\ \text{=}\frac{\text{5}}{\text{2}}\text{4-3}\\ \text{=10-3}\\ \text{=7}\end{array}$

Substituting t
