00:00Here we're giving the equation, x is equal to 4 plus iota
00:03And we have been asked the value of this question.
00:05So now we simply do nothing, first find x square and x cube
00:10So x is 4 plus iota, so squared for x squared
00:15the whole square of a plus b, a squared 16, iota squared minus 1 plus 2a squared plus 8
00:23iota
00:23So this becomes x squared 15 plus 8 iota
00:27In this way, the value of x squared in x cube will be obtained, it will be multiplied by x.
00:32So 15 plus 8 iota multiplied by 4 plus iota
00:3515 plus 4 plus 60 plus 15 iota plus 8 plus 32 iota
00:43iota into iota minus 1 becomes minus 8
00:47So this becomes right here is equal to 60 minus 8 52
00:54plus 32 plus 32 to the 59 iota of 0, 32 plus 15 iota
00:58That means 52 plus 47 iota. Now we will solve this further by entering the values.
01:03So first, x cubed means 52 plus 47 iota.
01:09plus 2 x square means plus 30
01:13This is 2 multiplied by you plus 16 iota
01:17minus yes 63 into x means 63 forza
01:236 forza 24 3 forza 12 means 252 minus 63 iota plus 171
01:33So this 47 plus 16 becomes 63 iota
01:37This cancellation from this 63
01:4052 plus 30 becomes 82
01:44And if we add 171 to 82, then
01:49Add 80 to 170 but it will become 250
01:54And in this 21 became 3 i.e. 253
02:02253 minus how did this come 252
02:07So if we subtract 252 from 253, we get 1 in our part.
