Answer 3

yes im sorry thats the wrong one

Answer 4

i meant these questions

Answer 5

we can write this:
\[\Large \begin{gathered}
{i^2} = - 1 \hfill \\
\hfill \\
{i^4} = {i^2}{i^2} = \left( { - 1} \right) \times \left( { - 1} \right) = 1 \hfill \\
\hfill \\
{i^5} = {i^4}i = ... \hfill \\
\hfill \\
{i^{17}} = {\left( {{i^4}} \right)^4}i = ... \hfill \\
\hfill \\
{i^{265}} = {\left\{ {{{\left( {{i^4}} \right)}^4}} \right\}^4}{i^9} = {\left[ {{{\left\{ {{{\left( {{i^4}} \right)}^4}} \right\}}^4}} \right]^4}{\left( {{i^2}} \right)^4}i = ... \hfill \\
\end{gathered} \]
please complete

Answer 6

1. 1^5 , i^17 , I^265 = D
2.7i E
3.-10 G
4. 5/2 I

Answer 7

oops...
\[\Large {i^{265}} = {\left[ {{{\left\{ {{{\left( {{i^4}} \right)}^4}} \right\}}^4}} \right]^4}{i^9} = {\left[ {{{\left\{ {{{\left( {{i^4}} \right)}^4}} \right\}}^4}} \right]^4}{\left( {{i^2}} \right)^4}i = ...\]

Answer 8

\[\Large 2i + 5i = i\left( {2 + 5} \right) = ...\]

Answer 9

the second one equal 7i

Answer 10

lol i did all the work i jst want to see if im right

Answer 11

\[\Large \left( {2i} \right) \times \left( {5i} \right) = 2 \times 5 \times i \times i = 10{i^2} = ...\]

Answer 12

please compare my answers with yours

Answer 13

\[\Large \frac{{5i}}{{2i}} = \frac{5}{2}\]

Answer 14

ok thank you very much

Answer 15

\[\Large \left( {3 + 2i} \right) + \left( {15 - 8i} \right) = \left( {3 + 15} \right) + i\left( {2 - 8} \right) = 18 - 6i\]

Answer 16

\[\Large \left( {3 + 2i} \right) - \left( {15 - 8i} \right) = \left( {3 - 15} \right) + i\left( {2 + 8} \right) = - 12 + 10i\]

Answer 17

ok thank i was correct

Answer 18

\[\large \left( {3 + 2i} \right) - \left( {15 - 8i} \right) = \left( {3 - 15} \right) + i\left( {2 + 8} \right) = - 12 + 10i\]

Answer 19

i have to log off thank you so much for the help
