Alright! In order to find the answer, we first must know what a square root is. A square root a number that is multiplied by itself in order to give you a product. So, we must find the two numbers that are less than 70 and more then 70 when squared. So:
8 x 8 = 64 and 9 x 9 = 81.
And so, the square root of 70 is between the numbers 8 and 9.
We use this same concept when finding what numbers the square root of 10 lies:
3 x 3 = 9 and 4 x 4 = 12.
The square root of 10 is between the numbers 3 and 4.
