Is there a square root of -28?
No, there is no real number that satisfies the equation √(-28). The square root of a negative number is not defined in the real number system. However, if we extend our number system to include complex numbers, we can define a square root of -28 as √(-28) = 2√7i, where i is the imaginary unit.
Is the square root a 2 an irrational number?
Yes, the square root of 2 is an irrational number.
What is the square root of the number square root of which is 2?
.5
Prove that square root of 2 is an irrational number?
The square root of 2 is 1.141..... is an irrational number
Is the square root of four a real number or a rational number or an irrational number or integers or a whole number?
The square root of four is a real number because it is a non-negative number that can be expressed on the number line. It is also a rational number because it can be expressed as the fraction 2/1. In fact, it is both a real number and a rational number, as all rational numbers are also real numbers.
The nonnegative square root of a number?
The unique nonnegative square root of a nonnegative real number. For example, the principal square root of 9 is 3, although both -3 and 3 are square roots of 9.
What is it example of a real number that is not a rational number?
the square root of 2
A number that is real and irrational?
Square root of (2) Pi
What is an Example of a real number that is not a rational number?
pi, or the square root of 2.
Is the square root of 4 a real number?
Yes. The square root of 4 is 2, because 2 times itself is 4.
What is the quare root of -1?
The square root of -1 is not a real number like -2.5, 0, or 5. Instead, it is and imaginary number, i, and i = the square root of -1. The answer is imaginary because you can never take a real number, square it, and get a negative number. However, i^2 = -1.
What is the square root of Ab2?
The square root of Ab^2 is |b|√A, where A is a positive real number and b is any real number. The absolute value of b is taken to ensure the result is always positive or zero. If b is negative, the result will be |b| times the square root of A.
What is an example of a real number that is not rational?
The square root of 2 is real number but it is not rational number because it can't be expressed as a fraction.
Is there a square root of -28?
No, there is no real number that satisfies the equation √(-28). The square root of a negative number is not defined in the real number system. However, if we extend our number system to include complex numbers, we can define a square root of -28 as √(-28) = 2√7i, where i is the imaginary unit.
Is every real number also a rational number?
No. "Pi", "e", and the square root of 2 are all real and irrational.
Is the square root of 2 a rational number?
No because it can't be expressed as a fraction and so therefore the square root of 2 is an irrational number.
Is the square root of -4 irrational?
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.
