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.
