What is the value of the expression when n = 3?

inysia [295]

The value of expression when n = 3 is 22

Solution:

Given expression is:

$\frac{6(n^2 + 2)}{n}$

We have to find the value of expression when n = 3

Substitute n = 3 in given expression

$\rightarrow \frac{6(3^2 + 2)}{3}\\\\Simplify\ the\ above\ expression\\\\\rightarrow \frac{6(9+2)}{3}\\\\Solve\ the\ terms\ inside\ the\ bracket\\\\\rightarrow \frac{6(11)}{3}\\\\Divide\ 6\ by\ 3 \\\\\rightarrow 2 \times 11 = 22$

Thus the value of expression when n = 3 is 22
