Best Answer

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

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


Can you find irrational numbers between 7 and 8?

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 an irrational square root?

An irrational number is a number that never ends. An example of an irrational square root would be the square root of 11.
