Question

Please show me the steps to solve this 2n^2 = -144

Answer 1

Answer: $\large \boldsymbol{} \pmb{6\sqrt{2} i}$

Step-by-step explanation:

$\large \boldsymbol{} \bf i=\sqrt{-1} \\\\ 2n^2=-144 \\\\n^2=-72 \\\\n=6\sqrt{2} i$

Answer 2

$\\ \sf\longmapsto 2n^2=-144$

$\\ \sf\longmapsto n^2=\dfrac{-144}{2}$

$\\ \sf\longmapsto n^2=-72$

$\\ \sf\longmapsto n=\sqrt{-72}$

$\\ \sf\longmapsto n=8.4i$
