Because the ancients were trying to find the measure of the diagonal of a square with sides of length one unit. The diagonal would not come out as any rational number and so Irrational Numbers - including square roots - had to be invented.
Square roots were not invented by any specific mathematicians, but they were discovered and studied by ancient civilizations such as the Babylonians, Egyptians, and Greeks. The concept of square roots emerged as a natural result of solving mathematical problems and practical applications involving squares and their areas. Over time, mathematicians like Pythagoras and Euclid contributed to the understanding and development of square roots.
Primes were known to the early Greek Mathematicians - the Pythagoreans about 400BC and Euclid about 300BC. Eratosthenes came up with 'the sieve of Eratosthenes' for working out primes about 200BC. There is no record that the Babylonians knew about primes.

Astronomers and astrologers were the ancient numerical calculators. their intellectual works had major influence and motivation for advances in mathematics. The traditional astrologer community "Ganaka" was the real mathematicians of ancient Kerala. Non European roots of mathematics extends up to them. Their lore was later learned by many other classes.

Since this ended up in the Mathematics section, there is an outside chance you meant to write square root. The square root of 9 is 3. The square root of 25 is 5. If you didn't mean to write square root, please resubmit your question and direct it to the proper section.
The perfect squares up to 120 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100
It depends on what type the plant is, The roots will start to grow just a little before the stem comes up. or The embryo or the shoot will came first then the roots.
the square roots are 2*2=4 3*3=9 4*4=16 5*5=25 6*6=36 7*7=49 8*8=64 9*9=81 10*10=100
2005. That was when the album X&Y came out, with the song on it.
Rene Descartes came up with the word imaginary in 1637 to describe them. It was a derogatory term. He (and many other mathematicians of that age) did not like imaginary numbers. Many people didn't believe in them, because they were not real.
I just bid one. I came up with $8.48 per square foot. Service and panels were not included. They are existing.
When (if) you learn more advanced mathematics you will find that there are, in fact 3 cube roots for any non-zero number (in the complex field). In general, there are n nth roots (de Moivre's theorem). However, only one of the cube roots can be a real number, the other two are complex numbers. The reason is that the product of a pair of negative numbers is positive. As a result both x and -x are square roots of x^2. But the product of three negative numbers is itself negative, so for cube roots the signs match up.
