How do you simplify 3 divided by 5 minus 2i?
0.6-2i?
What is 2-4i over 4 plus 2i put in the form of a plus bi?
To solve this type of problem, multiply both the numerator and denominator by the conjugate of the denominator. (2 - 4i) / (4 + 2i) = (2 - 4i)(4 - 2i) / (4 + 2i)(4 - 2i) then expand all the terms, and simplify. = (8 - 20i + 8i2) / (16 - 4i2) = (8 - 20i - 8) / (16 + 4) = -20i / 20 = -i Which in the required answer format becomes, 0 + i.
Simplify the imaginary number square root of negative twelve?
-12 = 4 x 3 x -1 so sqrt = 2i root 3
How do you divide complex numbers?
When dividing complex numbers you must:Write the problem in fractional formRationalize the denominator by multiplying the numerator and denominator by the conjugate of the denominator.You must remember that a complex number times its conjugate will give a real number.a complex number 2+2i. the conjugate to this is 2-i1. Multiply both together gives a real number.(2+2i)(2-2i) = 4 -4i + 4i + (-4i2) (and as i2 = -1) = 8To divide a complex number by a real number simply divide the real parts by the divisor.(8+4i)/2 = (4+2i)To divide a real number by a complex number.1. make a fraction of the expression 8/(2+2i)2. multiply by 1. express 1 as a fraction of the divisor's conjunction. 8/(2+2i)*(2-2i)/(2-2i)3. multiply numerator by numerator and denominator by denominator.(16-16i)/84. and simplify 2-2i
What does 7i divided by 2 plus 2i equal?
1.75 + 1.75i7i/2 + 2i = 3.5i + 2i = 5.5i
How do you simplify 3 divided by 5 minus 2i?
0.6-2i?

What is 2-4i over 4 plus 2i put in the form of a plus bi?
To solve this type of problem, multiply both the numerator and denominator by the conjugate of the denominator. (2 - 4i) / (4 + 2i) = (2 - 4i)(4 - 2i) / (4 + 2i)(4 - 2i) then expand all the terms, and simplify. = (8 - 20i + 8i2) / (16 - 4i2) = (8 - 20i - 8) / (16 + 4) = -20i / 20 = -i Which in the required answer format becomes, 0 + i.
How do you factor 24uv plus 35u² -30u³-28v?
24uv + 35u2 - 30u3 - 28v = 24uv - 28v - 30u3 + 35u2 = 4v*(6u - 7) - 5u2(6u - 7) = (4v - 5u2)*(6u - 7)
Simplify the imaginary number square root of negative twelve?
-12 = 4 x 3 x -1 so sqrt = 2i root 3
What is 9-12u 4 6u-5?
i meant 9+-12u+4+6u>-5, but wiki keeps changining it
What is 2i squared?
This is calculated as follows: (2i)2 = 2i x 2i = 4i2 = 4(-1) = -4.
What is the conjagate of 6-2i?
It is 6+2i. But -6-2i will also serve.
