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 =...
Unrivaled experience and resources to solve the toughest scientific and engineering challenges. Exponent brings together the world's best science and engineering with the most pressing problems facing companies, communities, and individuals.
Exponent is also known as the power of a number and in this case, it is read as 3 to the power of 4. Exponents can be whole numbers, fractions, negative numbers, or decimals.
When an exponent is a positive integer, that exponent indicates how many copies of the base are multiplied together. For example, 35 = 3 3 3 3 3 = 243. The base 3 appears 5 times in the multiplication, because the exponent is 5. Here, 243 is the 5th power of 3, or 3 raised to the 5th power.
While a positive exponent tells us how many times to multiply a base by itself, a negative exponent tells us to take the reciprocal (or ‘flip’) of the base raised to its corresponding positive exponent.
This free exponent calculator determines the result of exponentiation, including expressions that use the irrational number e as a base.
Superscript symbols are Unicode text characters that display slightly above the normal text line and are typically used to show exponents, ordinal-style notation, and small reference markers in plain text.
Exponent can also refer to someone who is an advocate, but it tends to refer especially to someone who stands out as a shining representative of something. In addition, it has kept its earlier meaning of “one who expounds,” as well as its mathematical symbol meaning.
