The square root of 2 is 1.141..... is an irrational number
Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).
Square root of 2= 1 You should know this idiots!
The opposite of a square root is the square of a number. In mathematical terms, if the square root of a number x is denoted as √x, then the opposite of the square root (√x) is x itself. This is because squaring a number undoes taking the square root of that number.
The square root of 2 is an irrational number
The square root of 2 squared is 2. sqrt(22)=2 The square root function and the exponent 2 and opposite function and cancel each other out. 22=4 sqrt(4)=2 =>sqrt(22)=2 What is the (square root of 2) squared - If you take the square root of a number then square it the answer is the number itself, so the answer is 2! What is the square root of (2 squared) - Looking at the question another way, if you take a number and square it, the square root of the resulting answer is the number itself, so the answer is 2! Unless, of course, this is a trick question . . . ivj
By root, I think you mean square root. The square root of 2 is approx. 1.414. The square root of 9 = 3, so this goes exactly at 3 on the number line. Square root 2 will be less than 1/2 way between 1 and 2 on the number line.
The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.
Since the square root of a number is the "number times itself that equals the original number," it makes sense that the larger the original number, then the larger the square root. The value of the square root of 2 will be greater than the value of the square root of 1.5.
Take the square root of the square root of the number (that is the fourth root of the number), for example: √√16 = √(√16) = √4 = 2 24 = 16 ⇒ 2 is the fourth root of 16.
