All prime numbers have irrational number square roots, so if you try to find the square root of a non-perfect square number use them to simplify it. For example,
±√125 = ±√25*5 = ±5√5 (when you want to show both the square roots)
√72 = √36*2 = 6√2
√-27 = √-9*3 = 3i√3

What type of problems have imaginary numbers?
Imaginary numbers are only ever used when you are using the square roots of negative numbers. The square root of -1 is i. You may find imaginary numbers when you are finding roots of equations.
When comparing fractions and square roots it is best to use your calculuator to find the decimal number?
Fne if they are sufficiently far apart. Otherwise, you may be better off squaring all the numbers. The smaller numbers will still have the smaller squares and at least you won't have irrational numbers to deal with.
How do you find three irrational numbers between 4 5?
Any number that can't be expessed as a fraction is an irrational number as for example the square root of 4.5
How do you find an irrational number between two irrational numbers?
There may be many easier and better ways, but here's how I would do it: -- Square the first given irrational number. -- Square the second irrational number. -- Pick a nice ugly complicated decimal between the two squares. -- Take the square root of the number you picked. It's definitely between the two given numbers, and it would be a miracle if it's not irrational.
Can you find irrational numbers between 7 and 8?
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
Can the rational zero test be used to find irrational roots as well as rational roots?
Rational zero test cannot be used to find irrational roots as well as rational roots.

What is the cube root of 6 in fraction?
Most square roots, cube roots, etc. - including this one - are irrational numbers. That means you can't write them exactly as a fraction. Of course, you can calculate the cubic root with a calculator or with Excel, then find a fraction that is fairly close to it.
When comparing fractions and square roots it is best to use your calculuator to find the decimal number?
Fne if they are sufficiently far apart. Otherwise, you may be better off squaring all the numbers. The smaller numbers will still have the smaller squares and at least you won't have irrational numbers to deal with.
Are square roots always whole numbers?
NO try and find the square root of 3. don't hurt yourself.

How do you find the square root of an irrational numbers?
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.
Can you find irrational numbers between 7 and 8?
72 = 49 and 82 = 64. So, the square root of any integer between these two numbers, for example, sqrt(56), is irrational.
Does a square root have to be a whole number?
No, a square root doesn't have to be a whole number. The square root of 2.25 is 1.5. It could be said that most square roots are not whole numbers. Take just the first few integers (counting numbers). Find the square roots of the numbers 1 through 10 and you'll find three of the numbers have whole number square roots (1, 4 and 9). The other seven don't. For the numbers 11 through 20, there is only 1 number with a whole number square root (16).
When were irrational numbers founded?
Probably when people tried to find the length of the diagonal of a unit square [sqrt(2)].
What mathematicians came up with square roots and why?
Because the ancients were trying to find the measure of the diagonal of a square with sides of length one unit. The diagonal would not come out as any rational number and so irrational numbers - including square roots - had to be invented.
