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.
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.
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 perfect squares up to 120 are: 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100
A quadratic function can have up to two roots. Depending on the discriminant (the expression under the square root in the quadratic formula), it can have two distinct real roots, one repeated real root, or no real roots at all (in which case the roots are complex). Therefore, the total number of roots, considering both real and complex, is always two.
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.
I just bid one. I came up with $8.48 per square foot. Service and panels were not included. They are existing.
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.
