When a number is expressed with exponents, or one number to a power of another, it is considered to be in index form. For example, 27 can be written in index form as 3^3. This is because 27 is 3x3x3 or 3^3. A common question in math will be to write a number in index form using a different number as base. The INDEX function. The basic INDEX function returns a VALUE based on a defined array / column and a row number. The syntax from Excel is as follows: =INDEX ( array , row number) Below is an example of using INDEX to return the value “Shirts,” assuming that you already know that the value is three cells down on your defined array. Using INDEX MATCH. The INDEX MATCH function is one of Excel's most powerful features. The older brother of the much-used VLOOKUP, INDEX MATCH allows you to look up values in a table based off of other rows and columns. And, unlike VLOOKUP, it can be used on rows, columns, or both at the same time.. INDEX MATCH is so useful that many Excel pros use it to replace VLOOKUP entirely, never relying An Example: Simplify 2-2: Rule 3: To multiply expressions with the same base, copy the base and add the indices. An Example: Simplify : (note: 5 = 5 1) Rule 4: To divide expressions with the same base, copy the base and subtract the indices. An Example: The INDEX-MATCH formula is an example of a simple nested function where we use the result from the MATCH function as one of the arguments for the INDEX function. The example below shows this being done in two separate steps. Syntax and Notes for MATCH and INDEX MATCH returns the position number of a matched value within the lookup range. Math explained in easy language, plus puzzles, games, quizzes, worksheets and a forum. For K-12 kids, teachers and parents. The exponent (or index or power) of a number says how many times to use the number in a multiplication. 10 2 means 10 × 10 = 100 (It says 10 is used 2 times in the multiplication)

## An Example: Simplify 2-2: Rule 3: To multiply expressions with the same base, copy the base and add the indices. An Example: Simplify : (note: 5 = 5 1) Rule 4: To divide expressions with the same base, copy the base and subtract the indices. An Example:

To manipulate expressions, we can consider using the Law of Indices. These laws only apply to expressions with the same base, for example, 34 and 32 can be  Index Laws. 2007 Maths IA, IMA & Intro. Fin. Maths I Revision/2. (3) In general (ab )n = anbn . For example,. (3x2y)3 = 33(x2)3y3 = 27x6y3. Exercises. 1. Simplify  43 is read as '4 to the power 3' or simply '4 cubed'. Example 2. Write each of the following expanded forms in index form: Solution: Example 3. Indices are a convenient tool in mathematics to compactly denote the process of taking a power or a root of a Solved Examples on Laws of Indices, Exponents. In many applications of mathematics, we can express numbers as powers of some given base. We can reverse this question and ask, for example, 'What power  is generally accompanied by an index that varies to encompass all terms that must be considered in the sum. For example, the sum of first whole numbers can   how to answer exam questions involving indices including fractional and negative powers, examples and step by step solutions, GCSE Maths.

Squares and Odd Numbers; Tens Complement The variable of summation is represented by an index which is placed beneath the summation sign. The index is often represented by i. (Other common possibilities for representation of the index are j and t.) The index appears as the expression i = 1. The index assumes values starting with the value on the right hand side of the equation and

## Indices & the Law of Indices Introduction. What are Indices? The expression 2 5 is defined as follows: We call "2" the base and "5" the index. Law of Indices. To manipulate expressions, we can consider using the Law of Indices. These laws only apply to expressions with the same base, for example, 3 4 and 3 2 can be manipulated using the Law

You'll work to understand  Stock A, for example, has a share price of \$3, and there are 50 shares of this stock in the index, so its market value is \$150 (\$3 X 50 shares = \$150). The total  is very common in mathematical expressions involving exponents, indexes, and in 1 Introduction; 2 More detailed examples; 3 Operators using subscripts and some types of mathematical symbols, in the integral included in the example  Gittins indices are hard to compute. This paper offers a good overview of various algorithms:  It makes the first division first. An ambiguous example with exponents. So, Mathematica does things from the left. Lets look now at exponents. What is 3^3^3
