An index number is defined as the number which is raised to the power. The power says how many times the number is to be used in multiplication. Generally, it is represented as a small number to the right side and above the base number. In the above example, the little “3” says to use 8 three times in multiplication. It is read as “ 8 to the power ...
Following are some of the exponent or index rules. These are basic rules of: Rule 1:When two numbers with the same base are multiplied, their powers get added. Example: \[ 2^{4} * 2^{2} =(2*2*2*2)(2*2)\] \[= (2*2*2*2*2*2)\] \[ = 26 = 2^{(4+2)}\] Rule 2:When two numbers with the same base are divided, their powers get subtracted. Example: \[ \frac{3...
Following are some of the index notation examples: 1. Express the prime factors of 98 in index notation form. Solution: Prime factors of 98 are = 2×7×7×7×7×7×7×7 Prime factors of 98 in index notation can be represented as 2×72 2. Evaluate \[ \frac{81}{16}^{-\frac{3}{4}}\] Solution: \[ \frac{81}{16}^{-\frac{3}{4}}\] \[ = \frac{1}{\frac{81}{16}^{\fra...
The distance light travels in one year can be easily calculated in the form of index notation as 9.461 × 10¹⁵. Index Notation is also known as exponential form or exponential notation.
Index Notation and Powers of 10. The exponent (or index or power) of a number says. how many times to use the number in a multiplication. 102 means 10 × 10 = 100. (It says 10 is used 2 times in the multiplication) Example: 10 3 = 10 × 10 × 10 = 1,000. In words: 10 3 could be called "10 to the third power", "10 to the power 3" or simply "10 ...

In computing. In several programming languages, index notation is a way of addressing elements of an array. This method is used since it is closest to how it is implemented in assembly language whereby the address of the first element is used as a base, and a multiple (the index) of the element size is used to address inside the array.
In standard form, numbers are recorded as a number between 1 and 10 multiplied by a power of ten. This is also called standard index form or scientific notation. Write the number as a value ...
