“This is because to square a number just means to multiply it by itself. For example, (−2) squared is (−2)(−2)=4. Note that this is positive because when you multiply two negative numbers you get a positive result.” – This, of course, is the exact opposite of what was asked, but it’s the given response.

Rational behavior is the cornerstone of rational choice theory, a theory of economics that assumes that individuals always make decisions that provide them with the highest amount of personal utility. These decisions provide people with the greatest benefit or satisfaction given the choices available.

The negative sign on an exponent means the reciprocal. Think of it this way: just as a positive exponent means repeated multiplication by the base, a negative exponent means repeated division by the base.

Rule 2: A negative number times a positive number equals a negative number. When you multiply a negative number to a positive number, your answer is a negative number. It doesn’t matter which order the positive and negative numbers are in that you are multiplying, the answer is always a negative number.

In mathematics, a square is the result of multiplying a number by itself. Squaring is the same as raising to the power 2, and is denoted by a superscript 2; for instance, the square of 3 may be written as 32, which is the number 9.

Zero squared is still equal to zero because zero times any real number is zero. Squaring a number simply means to multiply it by itself, or to raise it to the exponent of two. For example, zero squared can be written as 0*0 or 02. They are small numbers written over a base number.

Zero has one square root which is 0. Negative numbers don’t have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can’t be written as the quotient of two integers.

Any number times zero results in zero, it can never equal 2.

The cube root of 8 is written as 3√8=2.

Steps to find Cube Root Easily

Cube root of 729, 3√729 = 9.

Originally Answered: Is 3√8 a rational or irrational number? It’s definitely irrational. It’s the same as , and if that’s a rational number (call it ) then , which we already know to be irrational.

Real numbers have two categories: rational and irrational. If a square root is not a perfect square, then it is considered an irrational number. These numbers cannot be written as a fraction because the decimal does not end (non-terminating) and does not repeat a pattern (non-repeating).
