Question

Express this in a+ib form (1 - i )4

Answer 1

Hi

here is your answer ,

★ complex number ★

Q. Express this in a + ib from ( 1 - i )⁴

Answer:-
_______

( 1 - i )⁴

= { ( 1 - i )² }²

= { ( 1² - 2.1.( i ) + i² }² [ °.° ( a - b )² = a² - 2ab + b² ]

= ( 1 - 2i - 1 )² [ we know that , i² = - 1 ]

= ( - 2i )²

= 4i²

= -4

so

-4 + i.0 is the answer , where

a = - 4

b = 0

hopes I helped

Answer 2

hey there

here is your ans ..
◆◆◆◆◆◆◆◆

hope its correct
●●●●●●●●●●●●
(1-i)^4
{(1-i)^2}^2
{(1+i^2-2i)}^2
{(1-1-2i)}^2
(-2i)^2
4i^2
(-4)=-4+0i
where a=-4 and b=0

>>this is in the form of a+ib where
a is equal to-4
●●and●●
b is equal to 0
