### What is the square numbers between 10 30?

The square numbers between 10 and 30 are the numbers 16 and
25.
A square number is an integer that is the square of another
integer. Sometimes, these numbers are called perfect square. For
instance, 4 is a perfect square, because it can be found by
squaring the number 2.
The way to find these numbers it to work backwards. The closest
integer that can be squared to result in a number near 10 is 3 (32
= 9)
Now we simply work our way up the integers until the result of
the squaring is greater than 30.
42 = 16
52 = 25
62 = 36--Too far.
So the perfect squares between 10 and 30 are 16 and 25.

###### Asked in Math and Arithmetic

### Which 4 consecutive numbers total between 30 and 38?

6+7+8+9 =30
7+8+9+10 =34
8+9+10+11=38
However, as the totals 30 and 38 are not between 30 and
38, the only set of 4 consecutive numbers that comes to a total
that is between 30 and 38 is the second set, 7+8+9+10, which
total 34, a number that is clearly between the numbers 30
and 38.
Some might argue that 30 is a number between 30 and 38. If this
is so, then the question "What is the number between 5 and 7?"
could have the answer 5,6 or 7! But this is clearly incorrect!

### How do you find an irrational number between the twin primes 5 and 7?

Square them both, find a non-square integer between those two
results, and then take the square root of that number.
In other words, find a non-square integer between 25 and 49, and
since there is only one square number between them, 36, that should
be easy; let's pick 42, and then take the square root of it.
Ta da! âˆš42 is an irrational number between 5 and 7, its first
30 digits being 6.48074069840786023096596743608.
