what id the difference between square and square root ?? please ans in detail
The square of a number is the number multiplied by itself.
for example, 32 = 9 and (-3)2 = 9
(a + b)2 = (a + b) (a + b) = a2 + b2 + 2ab
(a - b)2 = (a - b) (a - b) = a2 + b2 - 2ab
The square root of a number is the value,that when it is multiplied by itself gives the number.
THEY ARE INVERSE OF THEMSELVES.
The square usually has two answers because not only does 2² = 4, so does (-2)² so -2 os also a square root of 4.
It is usually written √4 = ±2 meaning positive or negative 2.
Actually square and square root are the same process, called exponentiation, just raising a number to a different exponential power. "Squaring" a number means to raise that number to the power of 2. The square root means raising it to the power of 1/2.
