How do you add a negative exponent?
If the bases are the same, add the exponents. Remember to keep in mind the rules for adding and subtracting negative numbers. If the bases are different but the exponents are the same, multiply the bases and leave the exponents the way they are. If there’s nothing in common, go directly to solving the equation.
How do you add exponents with the same base?
Remember, to add or subtract numbers that have exponents you must first make sure that the base and exponent of the two terms you are trying to add or subtract are the same. If they are the same, then all you have to do is add together their coefficients and keep the base and exponent the same.
What is the rule for negative exponents?
A negative exponent helps to show that a base is on the denominator side of the fraction line. In other words, the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice versa. For example, when you see x^-3, it actually stands for 1/x^3. Not too bad right?
What happens when you add 2 exponents with the same base?
Method 1: Adding Exponents With Same Base and Exponents
The general form of adding exponents with the same base and exponents is an + an = 2an. Let us look at example to understand this better. For example: 43 + 43 = 2(43) = 2 × 4 × 4 × 4 = 128.

Do exponents get added or multiplied?
Summary. When you multiply two numbers or variables with the same base, you simply add the exponents. When you multiply expressions with the same exponent but different bases, you multiply the bases and use the same exponent.
How do you combine negative and positive exponents?

How do you combine exponents?
First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same. This is because of the fourth exponent rule: distribute power to each base when raising several variables by a power.
How do you add powers together?
To add exponents, both the exponents and variables should be alike. You add the coefficients of the variables leaving the exponents unchanged. Only terms that have same variables and powers are added. This rule agrees with the multiplication and division of exponents as well.

What are the rules of exponents?
The exponent rules are: Product of powers rule — Add powers together when multiplying like bases. Quotient of powers rule — Subtract powers when dividing like bases. Power of powers rule — Multiply powers together when raising a power by another exponent.
How do you solve exponents with negative exponents?
In the case of positive exponents, we easily multiply the number (base) by itself, but in case of negative exponents, we multiply the reciprocal of the number by itself. For example, 3-2 = 1/3 × 1/3. Let us learn more about negative exponents along with related rules and solve more examples.
How do you add numbers with the same base and different exponents?
What are the 3 laws of exponents?
Laws of Exponents. When multiplying like bases, keep the base the same and add the exponents. When raising a base with a power to another power, keep the base the same and multiply the exponents. When dividing like bases, keep the base the same and subtract the denominator exponent from the numerator exponent.
How do you add and subtract indices?

What is the rule for adding and subtracting exponents?
Can you add two numbers with different exponents?
When the base of a term is a variable, it is necessary for the bases in all terms of the expression to contain the same variable in order to be added together. Adding variables with exponents when the variables are different, like in the example 2×8+5y8 2 x 8 + 5 y 8 , is not allowed in mathematics.

What is the rule for adding indices?
When expressions with the same base are multiplied, the indices are added. You could verify this by evaluating both sides separately. When expressions with the same base are divided, the indices are subtracted.
What are the 7 rules for exponents?
7 Rules for Exponents with Examples
- RULE 1: Zero Property. Definition: Any nonzero real number raised to the power of zero will be 1.
- RULE 2: Negative Property.
- RULE 3: Product Property.
- RULE 4: Quotient Property.
- RULE 5: Power of a Power Property.
- RULE 6: Power of a Product Property.
- RULE 7: Power of a Quotient Property.
What are the 5 rules of indices?
There are several laws of indices (sometimes called indices rules), including multiplying, dividing, power of 0, brackets, negative and fractional powers.
Why can’t you add two numbers with the same property?
Step 1. No you can’t. You can always add two quantities that have the same dimension but they have to be expressed in same units first. If you are given two quantities of the same dimension but with different units and are asked to add them, by adding just the numbers you will get a wrong answer!
