Is Root 2 Root 8 rational or irrational?
Answer: When two or more terms have same roots then we can simply multiply them. Here our result is a rational number i.e. 4 which can be expressed in p / q form where q ≠ 0. Hence, √2 * √8 is also a rational number.
Is 8 square root 2 a rational number?
It is the positive solution of the equation x2 = 8. We can express the square root of 8 in its lowest radical form as 2 √2….Square Root of 8.

Is the product of 2 and 8 rational or irrational explain?
16
The product of 8 and 2, which are both irrational numbers, is 16, which is rational.
Is √ 2 rational or irrational and why?
Specifically, the Greeks discovered that the diagonal of a square whose sides are 1 unit long has a diagonal whose length cannot be rational. By the Pythagorean Theorem, the length of the diagonal equals the square root of 2. So the square root of 2 is irrational!
Is the square root of 2 over 2 a rational number?
The square root of 2 cannot be expressed as the quotient of two integers, and therefore is called an irrational number.
Is the square root of 2 divided by 2 rational?
The Square Root of 2. The square root of 2 is irrational.
How can you tell if a square root is irrational?
To find a square root of an irrational number by hand, you must follow a process of guessing, adding and dividing. Each time you choose a new number or fraction, the number should move closer towards the irrational number’s square root and the guess becomes more accurate.
How do we know square root 2 is irrational?
The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414. This value is widely used in mathematics. Root 2 is an irrational number as it cannot be expressed as a fraction and has an infinite number of decimals. So, the exact value of the root of 2 cannot be determined .
How do you solve irrational square roots?
Rather than drawing pictures of squares to simplify irrational square roots, you can use the following procedure: 1. Find the largest perfect square that evenly divides the number under the square-root sign. 2. Use the fact that square roots multiply to simplify as the product of a whole number and an irrational square root.
Is the sum of 2 irrational numbers rational?
The sum of two irrational numbers, in some cases, will be irrational. However, if the irrational parts of the numbers have a zero sum (cancel each other out), the sum will be rational. “The product of two irrational numbers is SOMETIMES irrational.”.
