The square root of -4 is not irrational, it is imaginary. Irrational Numbers are numbers that cannot be expressed as a fraction, like the square root of 2. Irrational numbers, however, are a subset of real numbers. The square root of -4 however, is not even a real number because no real number, when squared, gives -4. Therefore the square root of -4 is an imaginary number.
In calculus, the root is expressed as 2i where iis the square root of -1.
No. It's +4 and -4.
The square root of 121 is 11 which is not an irrational number.
It is rational.The square root of 9 is 3 and it is a rational number
You can find the square root of an irrational number by approximating irrational square roots of them, after you use the calculator. (The calculator gives an approximate root also) For example,1. Approximate the square root of 4.3 to the nearest hundredth.Use the calculator, which shows 2. 0736444135.Since 3 < 5 round down to 2.07 and drop the digits to the right of 7.2. Approximate the negative square root of 10.8 to the nearest hundredth.Use the calculator, which shows -3.286335345Since 6 > 5 round up to -3.29 and drop the digits to the right of 8.
The square root of 753 is 27.441. If you put that in your caculator you will get 27.44084547..... That making it irrational because the numbers would go on. If you would to round the square root of 753 to the nearest hundredth you would get 27.441
[ square root of (4.1) ] is irrational. But [ square root of (4) ] is rational.
Sometimes it is and sometimes it isn't. The square root of 2 and the square root of 3 are both irrational, as is their product, the square root of 6. The square root of 2 and the square root of 8 are both irrational, but their product, the square root of 16, is rational (in fact, it equals 4).
It is rational. The root of a perfect square, such as 4, is rational; the root of any positive integer that is not a perfect square is an irrational number.
The square root of 4 is 2 which is a rational number
No, the square root is 4 so that means it is rational because it can be turned into a fraction!
The square root of 94 is an irrational number
