How do you add indices in maths
WebMay 29, 2024 · Here’s how you do it: 5^4 × 2^4 = ? First, multiply the bases together. Then, add the exponent. Instead of adding the two exponents together, keep it the same. 5^4 × 2^4 = 10^4 This is why it works: This is because of the fourth exponent rule: distribute power to each base when raising several variables by a power. WebIndices. Indices (or powers, or exponents) are very useful in mathematics. Indices are a convenient way of writing multiplications that have many repeated terms. Example of an Index. For the example 5 3, we say that: 5 is the base and. 3 is the index (or power, or exponent). 5 3 means "multiply 5 by itself 3 times".

WebWhen expressions with the same base are multiplied, the indices are added. Example We can write 76 × 74 = 76+4 = 710 You could verify this by evaluating both sides separately. … WebAddition and Subtraction of Powers It is obvious that powers may be added, like other quantities, by uniting them one after another with their signs. Thus the sum of a 3 and b 2, is a 3 + b . And the sum of a 3 - b n and h 5 -d 4 is a 3 - b n + h 5 - d 4 .
