How do you rationalize complex numbers?
you must multiply by the conjagate. which is the denominator with the middle sign changed....(5+6i)...conjagate= (5-6i)....
How do you calculate factors?
Read slowly. You must first find the smallest number that can be divided into the number you want to factor without leaving a remainder. Whatever the result is, you divide again by a number that allows you to divide it without leaving a remainder. You continue to divide until you have broken if you divide it any further the answer will be 1. The numbers that you have used to divide are then lined up side by side and you place periods (multiplication symbols) between each one. This symbolizes that in order to get the number you have just factored you must multiply the numbers in this way.
What is the LCD of 7 8 9?
To find the lcd of any set of numbers, you must find the lowest number which all of the numbers in the set can divide evenly into. For example, to find the lcd of 7,8, and 9, you must first see if there are any numbers that can divide by 2 of the three numbers in the set. An example of such a number is 56. 56/7 = 8 56/8 = 7 Once you have a number like this, the final step is to multiply that number by the other number in the set that does not divide into it (in this case, 9) 56x9 = 504 So, the lcd of 7, 8, and 9 is 504.
Can factors be decimals?
Factors must be whole numbers, not decimals.
Is 32 a prime number?
Not Prime32 is not a prime number. In addition to 1 and 32, 2 and some other numbers will divide into it evenly. In order to be prime, a number must be divisible only by 1 and itself. Because all even numbers are divisible by 2, all even numbers except 2 are composite numbers.32 is NOT a prime number.

What are positive square roots called?
They are called real numbers. Negative square roots must be complex numbers.
Can you divide a square into eight squares?
No. You can only divide a square into 4, 9, 16 etc (i.e. they must be square numbers.
What are the characteristics of a complex number?
A complex number must have a real and imaginary part. It can be in the form: a + bi i is an imaginary number and a and b are real numbers
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
Can two numbers have 16 as their GCF and 204 as their LCM?
No, they cannot. The GCF must evenly divide the LCM.
In math what does ''mean'' answer?
"Mean" means average. To get this, you must add the numbers and divide them by how many numbers there are. For instance, What is the mean of 29, 30, 67, and 52? Add them up to equal 178, then divide it by 4, which is 44.5.
Why is important to divide numbers?
because you must, in order to do the inverse operation of multiplication you must perform division. division makes the numbers smaller which is very important in certain equations and word problems.
What is the domain of the square root of x mulitplied by x-9?
To an extent, the answer depends on what the range is. The domain can be the set of complex numbers, with the range also the complex numbers. The domain can be the whole of the real numbers if the range can be complex. If the range needs to be real, then the domain must be the real numbers excluding the interval (0,9). As the range is restricted (rational, integer), the domain will also shrink.
Can you factor complex numbers?
Yes. Consider, if you can factor complex numbers, then logically, you should be able to take two complex numbers, multiply them together, and get a third. That can indeed be done. For example: (4i + 7)(3i + 2) = -12 + 8i + 21i + 14 = 29i + 2 Therefore, the complex number 29i + 2 must be divisible by 4i + 7 and 3i + 2.
Give the equation for determining the total impedance in a inductive and resistive circuit?
Simple addition, but it must be done with complex numbers.
What is the geometric mean of 32 and 4?
The mean is the average of a set of numbers. To find the average, you must add all the numbers in the set and divide that number by however many numbers are present in the set. For this example, you need to add 32 and 4 and then divide that answer by two, which is 18 in this case.
