An exponent is a number that tells how many times the base number is used as a factor. For example, 34 indicates that the base number 3 is used as a factor 4 times. To determine the value of 34, multiply 3*3*3*3 which would give the result 81. Exponents are written as a superscript number (e.g. 34) or preceded by the caret (^) symbol (e.g. 3^4).
The exponent in [math]4\cdot4\cdot4\cdot4\cdot4[/math] is 5. This can also be written as [math]4^5[/math]. Exponents are used in algebra. It is a number or symbol, placed above and to the right of the expression to which it applies, that indicates the number of times the expression is used as a factor.

Some Basic Facts about Exponents Two exponents acting on a given factor xa b = xab Example 1: = Example 2: 2 =2 = 2 =64 egative exponents = 1 Example 1: 3 = 3 =9 = ˘ Alternatively, you could write 3 = ˇ = ˘ Multiply two exponential factors xaxb = xa+b x BUT ax yb = cannot simplify x WORDS: Only if bases are same can you combine
Solving math problems with exponents or powers requires understanding the laws of exponents. Exponent examples include negative exponents, adding or subtracting exponents, multiplying or dividing exponents and exponents with fractions. Special exponent rules apply when the exponent is 0 or 1.
exponent, in mathematics, a number, letter, or algebraic expression written above and to the right of another number, letter, or expression called the base. In the expressions x2 and xn, the number 2 and the letter n are the exponents respectively of the base x.
Exponent facts for kids. Kids Encyclopedia Facts - Homework Help. An exponent tells you how many times a number (known as the base) is multiplied by itself. For example: if you see , 5 is the base and 7 is the exponent. Therefore, in this example, 5 is multiplied by itself 7 times e.g. .
An exponent is a number that tells how many times the base number is used as a factor. For example, 3 4 indicates that the base number 3 is used as a factor 4 times. To determine the value of 3 4, multiply 3*3*3*3 which would give the result 81.. Exponents are written as a superscript number (e.g. 3 4) or preceded by the caret (^) symbol (e.g. 3^4).
There once was a man named Euclid(u-cl-id) that you see in the picture above. He discovered the concept of exponents, which he used in his geometric equations, not algebraic equations which most people used them with. Later Archimedes generalized the idea of powers.
