8 0

Answer and Step-by-step explanation:

It says your question is : 9-16=? And the answer for that would be -10. But that's not there in the options I think your question was supposed to be meant like this : 16-9=? cause then it would be 7 tho it's there in the options, the sign is wrong it's not -7 it's  +7 or just 7.

Perform the indicated operations. Do the root of -48 in terms of i please
lubasha [3.4K]

Answer:

\frac{-5-\sqrt{-48}}{40}  in terms of i is: \frac{-1}{8}-\frac{i\,\sqrt{3}}{10}

Step-by-step explanation:

\frac{-5-\sqrt{-48}}{40}

We know that \sqrt{-1} = i

so,

\frac{-5-\sqrt{48}i}{40}

Now solving:

=\frac{-5}{40}-\frac{i\,\sqrt{48}}{40}\\=\frac{-1}{8}-\frac{i\,\sqrt{2*2*2*2*3}}{40}\\=\frac{-1}{8}-\frac{i\,\sqrt{2^2*2^2*3}}{40}\\=\frac{-1}{8}-\frac{2*2\,i\,\sqrt{3}}{40}\\=\frac{-1}{8}-\frac{4\,i\,\sqrt{3}}{40}\\=\frac{-1}{8}-\frac{i\,\sqrt{3}}{10}

So, \frac{-5-\sqrt{-48}}{40}  in terms of i is: \frac{-1}{8}-\frac{i\,\sqrt{3}}{10}
