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.
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.
Such a number does not exist.
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.

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.
Yes. A 17-digit number would be less than a quintillion.
There are an infinite number of prime numbers.
agazillion gazillion do not exist, they aren't numbers.
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)
That number does not exist since numbers go on infinitely.
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.
