00:00 - 00:59 | hi guys the question given here is write the conjugate of under root of minus 25 + x 7 + under root of minus 576 so let's simplify these terms minus under root of 25 x 7 + under root of 576 is the question and under root of minus 25 is 5i since we know that the value of Y is my of under root of 1 Sohail 5 x 7 + 576 is the square of 24 so where we will get 24i so what we will do here is we will multiply the 5i to the entire term given here so 5 x 7 |

01:00 - 01:59 | is 35 I + 5 X 24 is 120 so 120 I square so what's the value of I square here in this step will square both side so will get a square to be -1 so here we have 35 -120 I 4120 so in standard form we can write this to be - 120 + 35 so this version what we have to find we have to find the conjugate of disturb so the conjugate of disturb -120 + 35i is |

02:00 - 02:59 | can we find by reversing the sign of the imaginary term so here we will get our answer to be - of 120 - 35 I so this is our correct answer thank you |
