What is the square root of -70?
Ordinarily, the square root of -70 does not exist since a positive number squared or a negative number squared results in a positive number. If complex numbers are permitted, then the square root of -70 is i√70 ~= 8.367i where i is the imaginary square root of -1 such that i2 = -1.
Is non-real numbers exist?
no, every number is a real number --- There are numbers that are not real numbers. They are called imaginary numbers, and have the property that when they are squared, the result is negative. The square root of -1 is called i, and the square root of any other negative number is i times the square root of the absolute value of the number. So the square root of -4 is 2i.
Which two-digit number can you add to any number and it will change the value of the hundreds tens and units?
Such a number does not exist.
How do you you get the square root of 10?
It is best to do this on a calculator. If you want to do it without one, you can try different numbers, to see which number, when squared, is closest to 10. For example, 3 squared is 9, and 4 squared is 16, so the square root of 10 is obviously between those two. Faster methods exist, too.
What is the domain and range for y equals x squared?
y is greater than 0 x exist in a set of real numbers
Does 17 digits exist?
Yes. A 17-digit number would be less than a quintillion.
How much number's excist?
There is no way to determine the amount of numbers that exist. Unlike physical objects, numbers are not finite. There is literally no end to the amount of numbers that can exist.
How man prime number exist in mathematics?
There are an infinite number of prime numbers.
If you choose any phone number at random what is the probability the fourth digit will be 6?
It is best to assume independence between the numbers (i.e. the 4th doesn't affect the 5th)If that is true, then the odds are .1(We don't have to worry about area codes exist, or about avoiding 911, since this is the 4th digit)
What number is agazillion?
agazillion gazillion do not exist, they aren't numbers.
What is the highest number that can be spoken in words?
That number does not exist since numbers go on infinitely.
What is a number between 4900 and 3600 that is a square number and is a multiple of 15 and 5?
Such a number does not exist. 3600 is 60 squared and 4900 is 70 squared There is no number between 60 and 70 that is a multiple of 15 so there can be no square between 3600 and 4900 that is a multiple of 15.
