Consider the complex number z $=$ i$(4+2$i$).$ Recall that i is the imaginary unit, where i$2=1.$

$($a$)$ Consider the following commands.

$($i$)$

z$=$j$*(4+2*$j$)$

$($ii$)$

z$=$complex$(4,-2)$

$($iii$)$

z$=$j$(4+2$j$)$

$($iv$)$

z$=$complex$(-2,4)$

Determine which of the above commands gives a correct representation $(1)$ or NOT correct representation $(2)$ of the above complex number z$.$

So$,$ for example, if you think that the answers, in the above order, are Correct,Not Correct,Not Correct,Correct then you would enter $\text{'}1,2,2,1\text{'}$ into the answer box below $($without the quotes$).$
