Question

if n=2√3 find n²+1/n²​

Answer 1

Answer:

145/12

Step-by-step explanation:

n^2 = 12

12 + 1/12 = (144+1)/12 = 145/12

Answer 2

145/12

Step-by-step explanation:

${n}^{2} + \frac{1}{ {n}^{2} }$

${(2 \sqrt{3} )}^{2} + \frac{1}{(2 \sqrt{3})^{2}}$

$12 + \frac{1}{12}$

$\frac{12(12) + 1}{12} = \frac{145}{12}$

145/12
