Question

Please show me the steps to solve this

2n^2 = -144

Answer 1

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

`\\ \sf\longmapsto n^2=(-144)/(2)`

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

`\\ \sf\longmapsto n=√(-72)`

`\\ \sf\longmapsto n=8.4i`

Answer 2

Answer:
`\large \boldsymbol{} \pmb{6√(2) i}`

Explanation:

`\large \boldsymbol{} \bf i=√(-1) \\\\ 2n^2=-144 \\\\n^2=-72 \\\\n=6√(2) i`
