What is the easiest way to find the square root?
the eisest way to find square root of something , is to see what number x itself = that number .... so EXAMPLE:what is the square root of 81? this is how you will find it.....so what number x itself gives me 81? it's 9 because 9x9=81 so the square root of 81 is 9
What are the factors for number 70?
In order to find the factors of a number you first have to break it down into its prime factors. In this case, 70 can be broken down as follows: 70 = 2x5x7 To find other factors (apart from 1) you need to multiply any combination of these prime factors together. Doing this gives us the factors of 70 as: 1, 2, 5, 7, 10, 14, 35 and 70.
How do you know you have listed all the factors for a number?
If you know the prime factorization of a number, you can predict how many factors it has. Add 1 to each exponent of each prime factor and multiply. The product will be the number of factors. Example: The prime factorization of 30 is 2 x 3 x 5 Each of those factors has an implied exponent of 1. Add 1 to each and multiply. 2 x 2 x 2 = 8 30 has eight factors. Half of them will be less than the square root, half will be greater. The square root of 30 is between 5 and 6. By the rules of divisibility, you know that 30 is divisible by 1 (because everything is), 2 (because it's even), 3 ( because its digits add up to a multiple of 3), and 5 (because it ends in 0) Dividing those numbers into 30 gives you 30, 15, 10 and 6 Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30 That's how you know you got them all.
How many square feet does the amazon rainforest have?
The Amazon rainforest covers approximately 2.1 million square miles, which is equivalent to about 1.4 billion acres or 5.5 million square kilometers. To convert this to square feet, we would multiply 1.4 billion acres by 43,560 (the number of square feet in an acre). This gives us a total of approximately 61.1 trillion square feet in the Amazon rainforest.
How do i find the factors of a number over 60?
There are a few ways to go about factoring. You can decide what works best for you. I always find the prime factorization first. Let's look at a random number: 108 The prime factorization can be found by using a factor tree. 108 54,2 27,2,2 9,3,2,2 3,3,3,2,2 2^2 x 3^3 = 108 Half of the factors will be less than the square root, half greater. If the number is a perfect square, there will be an equal number of factors on either side of the square root. In this case, the square root is between 10 and 11. Adding one to the exponents of the prime factorization and multiplying them will tell you how many factors there are. In this case, the exponents are 2 and 3. Add one to each. 3 x 4 = 12 108 has 12 factors. Six of them are 10 or less, six of them are 11 or greater. All we have to do is divide the numbers one through ten into 108. If the result (quotient) turns out to be an integer, you've found a factor pair. Knowing the rules of divisibility will make that even easier. 108 is divisible by... 1 because everything is. 2 because it's even. 3 because its digits add up to a multiple of 3. 4 because its last two digits are a multiple of 4. 6 because it's a multiple of 2 and 3. 9 because its digits add up to a multiple of 9. That's six factors less than 10. Divide them into 108. That's the rest of them. (108,1)(54,2)(36,3)(27,4)(18,6)(12,9) 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108 Notice that all of those numbers, except for 1, can also be found in the prime factorization.
Which number can you square that gives an answer smaller than the number thought of?
3i where i is the square root of negative one.3i x 3i = -9
A square root of a number is one of its two equal factors?
That is correct. I would say, the square root of a number is another number that, when you multiply it by itself, gives you the number you started with. Remember that a positive number always has two square roots, one positive and one negative. The square roots of 49 are 7 and -7, since 7x7=49, and also -7x-7=49.
What is the number when multiplied by itself gives the stated number?
That is called the square root of a number.
What is the square root of243?
The square root of 243 is 15.58. The square root is the number that when factored gives that number. 15.58 squared is 243.
What do you call a number when multiplied by itself gives the stated number?
Square root
Can a negative number be a square?
the square is positive always.Except in the case of an Imaginary number. An imaginary number is a number that gives a negative result when squared,where i= √-1
How to find the square root of a number?
To find the square root of a number, you can use a calculator or a mathematical formula. The square root of a number is a value that, when multiplied by itself, gives the original number.
In 11 a square number?
No. A square number is one that has an integral as its square root. For example, 9 is a square number because 3 x 3 = 9. There is no whole number that gives you 11 when multiplied by itself.
What is the sqare root of -9?
The square root of a number is a number, which, when multiplied by itself, gives the original number. The square root of 9 is 3.
How do you find how to square a number to find an area?
To square a number, multiply the number by itself.Example: The square of 6 is (6 times 6) = 36.Note: This gives you the area only if the figure is a square.
Four times the square of a number is16 find the number?
a square root is a number that when multiplied by itself gives a particular answer. 4x?=16 4x "the square root of 16"=16..we choose 16 because its square is 4 and when multiplied by itself gives us the final answer 16.
What does square root of a number mean?
The square root of a number is a number which, when multiplied by itself, gives the original number. So, 9 has a square root which is 3 because 3*3 = 9
