The main difference between exponent and power is that exponent is the number to which a number is raised so as to define its power whereas power is defined for the whole expression of repeated multiplication that includes the base and the exponent.
Meaning of Exponents. Exponent is the way in which large numbers are expressed in terms of powers. For example, 4 multiplied 3 times by itself can be expressed as 4 × 4 × 4 = 4 3, where 3 is the exponent of 4. Observe the following figure to see how we express the exponent of a number.
Exponents. The exponent of a number says how many times to use the number in a multiplication. In 82 the "2" says to use 8 twice in a multiplication, so 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the power 2" or "8 to the second power", or simply "8 squared".
Exponents and powers are ways used to represent very large numbers or very small numbers in a simplified manner. For example, if we have to show 3 x 3 x 3 x 3 in a simple way, then we can write it as 34, where 4 is the exponent and 3 is the base. The whole expression 34 is said to be power.
Exponents are also called Powers or Indices. The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared". Try it yourself:
In short, power or exponent indicates the number of times a number needs to be multiplied by itself. Here, the base can be any integer, fraction or decimal. The exponent can also take up any value, be it positive or negative.
14 Νοε 2021 · We need a more sophisticated way in simplifying expressions with exponents raised to exponents with more than one factor in the base. Hence, taking a look at Example 6.1.8 , we can see the result is \(a^3 b^3\).
