Finding the square root of a number is the inverse operation of squaring that number. Remember, the square of a number is that number times itself. The perfect squares are the squares of the whole numbers. The square root of a number, n, written below is the number that gives n when multiplied by itself.
An irrational number is a real number that cannot be expressed as a ratio of two integers, pq/ where q > 0. sqrt(2) and pi are examples.
Irrational numbers, such as √2 or π, cannot be written as a fraction pq where p and q are integers and q is not equal to zero. These numbers cannot be expressed as a ratio of two integers and are non-repeating and non-terminating decimals.
