What is the difference between square roots and real square roots?
In mathematics, there is a distinction between real numbers and imaginary numbers. There is a number known as i which means, the square root of minus one. Since any number that we know of will produce a positive result when multiplied by itself, there would seem to be no such thing as the square root of minus one, however, the concept is useful for certain purposes, nonetheless, and it is therefore known as an imaginary number. Any multiple of i is also an imaginary number (such as 67i and so forth). So, some square roots are real numbers, and some are imaginary. Both types can be called square roots.
Rational numbers who square roots are whole numbers?
Every integer is a rational number, and some integers are perfect squares. These are the only rational numbers to have an integral square root.
Is square root rational or irrational?
The square roots of some numbers are rational: eg sqrt(4) = 2, sqrt(0.04) = 0.2, sqrt(400) = 20 The square roots of some numbers are irrational eg sqrt(2) = 1.414 (approx), sqrt(0.02) = 0.1414 (approx), sqrt(200) = 14.14 (approx) The square roots of negative numbers are neither rational nor irrational, but imaginary.
Numbers with square rootsthat are whole numbers?
Numbers with square roots that are whole numbers are called perfect squares. These include integers like 0, 1, 4, 9, 16, and so on, which can be expressed as the square of whole numbers (0², 1², 2², 3², 4², etc.). In general, any non-negative integer ( n ) that can be written as ( k² ) for some integer ( k ) is a perfect square.
Why are all square roots not irrational numbers?
Because some of them are squares of rational numbers. So their square roots are the rational numbers.Thus if x is rational, then the square roots of x2, which are -x and +x are both rational.
Is the square root are rational numbers?
Some square roots are rational but the majority are not.
Is 1.68 irrational?
no. irrational numbers are square roots of numbers that aren't square, pi, and some other numbers. irrational means it never ends.

What are some jobs or careers that involve using square roots?
Some jobs or careers that involve using square roots include mathematicians, statisticians, engineers, physicists, and financial analysts. These professionals often use square roots in calculations involving measurements, data analysis, modeling, and risk assessment. Understanding square roots is essential in fields that require complex mathematical computations and problem-solving skills.
Are irrational numbers square roots?
Usually they are. More specifically, if you take the square root of a positive integer, there are only two possibilities:* If you take the square root of a perfect square, you get a whole number. * In all other cases, you get an irrational number.

Is the square root of any whole number an integer ar an irrational number?
Some square roots of whole numbers are integers, some of them are irrational numbers. The square root of four for instance is a rational number, 2. The square root of two however is an irrational number, approximately 1.414211356.
What is the symbol for an irrational number?
There is no special symbol for an irrational number. However, it is known that many square roots, cubic roots, etc., as well as some special numbers such as pi and e, are irrational.
Numbers that cannot be expressed as a ratio of integers are called?
They are called irrational numbers; numbers that can be expressed as a ratio of integers are called rational numbers. Some common irrational numbers are pi (3.14159...) and the square root of two.
What are vegetables that are called roots?
Garlic, potatoes, and onions are some of the vegetables which are called roots.
