To find the quotient of the complex numbers ( (4 + 4i) ) and ( (5 + 4i) ), you divide the two:
[ \frac{4 + 4i}{5 + 4i}. ]
To simplify, multiply the numerator and denominator by the conjugate of the denominator:
[ \frac{(4 + 4i)(5 - 4i)}{(5 + 4i)(5 - 4i)} = \frac{(20 - 16i + 20i - 16)}{(25 + 16)} = \frac{(4 + 4i)}{41}. ]
This results in ( \frac{4}{41} + \frac{4}{41}i ).
The conjugate of a complex number is obtained by changing the sign of its imaginary part. For the complex number (8 + 4i), the conjugate is (8 - 4i).
(2 + 4i) - (7 + 4i) = -5 2 + 4i - 7 + 4i = -5 + 8i
The expression ( 4i ) represents a complex number where ( i ) is the imaginary unit, defined as ( i = \sqrt{-1} ). Therefore, ( 4i ) has a real part of 0 and an imaginary part of 4. In the complex plane, it is located 4 units above the origin along the imaginary axis. Its value is simply ( 4i ) in the context of complex numbers.
Since the imaginary parts cancel, and the real parts are the same, the sum is twice the real part of any of the numbers. For example, (5 + 4i) + (5 - 4i) = 5 + 5 + 4i - 4i = 10.
The absolute value of a complex number ( a + bi ) is given by the formula ( \sqrt{a^2 + b^2} ). For the complex number ( 2 + 4i ), the absolute value is calculated as follows: ( |2 + 4i| = \sqrt{2^2 + 4^2} = \sqrt{4 + 16} = \sqrt{20} = 2\sqrt{5} ). Thus, the absolute value of ( 2 + 4i ) is ( 2\sqrt{5} ).
The conjugate of a complex number is obtained by changing the sign of its imaginary part. For the complex number (8 + 4i), the conjugate is (8 - 4i).
the problem: what is 4 + 4i + 4 + 6i what you do is add the real and imaginary parts, thus: 4+4 and 4i+6i = 8+10i answer.
(x - 4i)(x + 4i) where i is the square root of -1
(2 + 4i) - (7 + 4i) = -5 2 + 4i - 7 + 4i = -5 + 8i
-9
The four roots of 4√256 are {4, -4, 4i, and -4i}. Note that two of them are real numbers and the other two are pure imaginary, therefore 0 + 4i is the same as just 4i
To get the conjugate simply reverse the sign of the complex part. Thus conj of 7-4i is 7+4i
('|x|' = Absolute value of x) |3+4i| = √(32 + 42) = √(9+16) = √25 = 5 Thus |3+4i| = 5.
-6-4i.
The conjugate of -8-4i is -8+4i. It is obtained by changing the sign of the imaginary part of the complex number.
The multiplicative inverse of a complex number is found by taking the reciprocal of the number. In this case, the reciprocal of 4i is -1/4i. To find the reciprocal, you divide 1 by the complex number, which results in -1/4i. This is the multiplicative inverse of 4i.
The expression ( 4i ) represents a complex number where ( i ) is the imaginary unit, defined as ( i = \sqrt{-1} ). Therefore, ( 4i ) has a real part of 0 and an imaginary part of 4. In the complex plane, it is located 4 units above the origin along the imaginary axis. Its value is simply ( 4i ) in the context of complex numbers.
