Adding Exponents – Examples & Techniques

Adding Exponents

Adding Exponents: Algebra is among the core training courses in maths. To comprehend algebra, it is essential to understand how to use backers and radicals. The addition of backers forms part of the algebra curriculum, and also, therefore, is vital for students to have a more robust structure in maths.

Many students frequently confuse the addition of backers with the addition of numbers and hence wind up making errors. These confusions usually entail the difference in the definition of terms such as exponentiation and also exponents.

Before diving right into pointers on exactly how to add exponents, let’s start by defining terms on backers. To begin with, a backer is just the duplicated multiplication of a number on its own. In maths, this procedure is referred to as exponentiation. Exponentiation is, for that reason, an operation entailing numbers in the form of b n, where b is described as the base as well as the number n is the exponent or index or power. For example, x4 consists of 4 as an exponent, and x is called the base.

Exponents are sometimes called powers of numbers. A backer stands for the variety of times a number is to be increased by itself. As an example, x4 = x × x × x × x.

How to Add Exponents?

To add backers, both the backers and variables should be matched. Go ahead and add the coefficients of the variables leaving out the exponents unchanged. Only terms that have the same variables and also powers are included. This rule conforms with the division and multiplication of exponents also.

Below are the steps for adding backers:

Make sure to check the terms if they have the same bases as well as backers.

For example, 42 +42, these terms have both the same base four and exponent 2.

Calculate each term individually if they either have a various base or exponent

For instance, 32 + 43, these terms have both various backers as well as bases.

Add the outcomes with each other.

Adding exponents with Varied bases and exponents

Including backers is done by computing each backer first and then adding: The general form such backers is: a n + b m.

Example 1

83+ 92= (8)(8)(8) + (9)(9) = 512 + 81 = 593

42+ 25= 4 ⋅ 4 +2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 = 16 +32 = 48

62+ 63= 252.

34+ 36= 81 + 729 = 810.

32+ 53= (3)(3) + (5)(5)(5) = 9 + 125 = 134

Adding exponents with same exponents & bases

The general formula is:

bn + b n = 2b n

Example 2

83+ 83+ 83 = 3(83) = 3 * 512 = 1536

52+ 52= 2(52) = 2 * 25 = 50

32+ 32= 2(32) = 2 * 9 = 18

42+ 42= 2⋅42 = 2⋅4⋅4 = 32

Adding variables with different exponents

Start to compute each exponent separately and then perform addition: xn + x m
