The answer depends on the power number. If, for example, the power number is -0.5, then there is no rule in real numbers.

What are the 6 rules of exponents?
ExponentsExponents are used in many algebra problems, so it's important that you understand the rules for working with exponents. Let's go over each rule in detail, and see some examples. Rules of 1 There are two simple "rules of 1" to remember. First, any number raised to the power of "one" equals itself. This makes sense, because the power shows how many times the base is multiplied by itself. If it's only multiplied one time, then it's logical that it equals itself. Secondly, one raised to any power is one. This, too, is logical, because one times one times one, as many times as you multiply it, is always equal to one. Product Rule The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. In this example, you can see how it works. Adding the exponents is just a short cut! Power RuleThe "power rule" tells us that to raise a power to a power, just multiply the exponents. Here you see that 52 raised to the 3rd power is equal to 56. Quotient Rule The quotient rule tells us that we can divide two powers with the same base by subtracting the exponents. You can see why this works if you study the example shown. Zero Rule According to the "zero rule," any nonzero number raised to the power of zero equals 1. Negative Exponents The last rule in this lesson tells us that any nonzero number raised to a negative power equals its reciprocal raised to the opposite positive power.This information comes from http://www.math.com/school/subject2/lessons/S2U2L2DP.html
Why do two negative numbers add together to make a positive number?
If you do -5+-5 you get -10 which is not a positive number. If you subtract two negative numbers you could get a positive depending on what number you are subtracting. E.G. -5 - -9 =4 which is positive. A good rule a thumb is -- goes up +- goes down.
How is the power of power property rule and the power of a product property rule different?
(xa)b = xa*b = xab (xy)a = xaya
What rule allows us to change the sign of an exponent?
1 divided by a number with an exponent is the same as the number to the exponent of opposite sign. For example 1 divided by 2 to the third power is the same as 2 to the minus 3 power
What is the rule for dividing integers?
When dividing numbers that are different the answer will be negative.
What is a rule for raising a negative number to a power?
It is the positive form of the number raised to that power, multpilied by -1 raised to that power.
What is the general rule for raising a number to the power of 1?
Raising a number to the power of 1 doesn't change the number.
Raising a product to a power exponent rule?
power of 0
Why is that negative number multiplied by a positive number a negative number?
Because that is the rule. negative * negative=positve positive *negative=negative and vice versa
What are the rule for dividing negative numbers?
The rules for dividing negative numbers is the same as multiplying them. A negative number multiplied/divided by a negative number is positive and a negative number multiplied/divided by a positive number is negative.
What is the rule for subtracting negative numbers?
The rule for subtracting negative numbers is 'when you are subtracting a negative number from a positive or negative, you must always add it.'Example: 3--3 = 3+3 = 6
Why does a negative integer raised to an even power always result in a positive integer?
The multiplication rule of thumb always states that a negative number times a negative number results in a positive number. Since an even number is always divisible by two, any value raised to an even integer power will result in a positive number. However, a basic proof is presented as follows: (-A) * (-A) = A^2 ((-A) * (-A)) ^ 2 = ((-A * -A) * (-A * -A)) = A^2 * A^2 = A ^ 4 ...
When adding a positive number to a negative number what is a good rule for determining the sign of the sum?
If the negative number is a bigger number, the answer will be negative. Conversely, if the positive number is bigger, the answer will be positive. -20+10= -10 (larger negative number) -10+20=10 (larger positive number)
What is the general rule for multiplying a decimal by a negative integer power of 10?
The decimal point is moved to the left by the value of the power.
When you multiply a negative number by a negative number is the number positive or negative?
Positive A simple rule to remember this is when multiplying two numbers with the same sign, the result is ALWAYS positive. When multiplying two numbers with different signs, the results is ALWAYS negative.
What is 12 -4?
16?
What is the rule for adding 2 negative integers?
The rule is if a number is positive you add them. EX: 4+4=8 But if the numbers are both negative... you forget the plus sign and just put the numbers together and use whatever sign they have. EX: -4-4= -8 you see? you are adding them put if they are negative, they go down the number line. not up. Just picture a number line, if you add a negative number to an already negative number, wouldn't the number go to the left? The answer is yes. Yes it would. :)
