exponent 🔊
Meaning of exponent
A person who supports or advocates for a particular idea, theory, or cause; in mathematics, a symbol written above and to the right of a number indicating how many times the number is multiplied by itself.
Key Difference
While 'exponent' can refer to both a person promoting an idea and a mathematical notation, its synonyms often specialize in one meaning or the other.
Example of exponent
- Marie Curie was a leading exponent of radioactive research in the early 20th century.
- In the equation 2³, the number 3 is the exponent, indicating that 2 is multiplied by itself three times.
Synonyms

- The lawyer served as an advocate for environmental protection laws.
proponent 🔊
Meaning of proponent

Example of power
- The expression 5^4 reads as '5 raised to the power of 4.'
- Calculating large powers is essential in cryptography.
index 🔊
Meaning of index
In mathematics, another term for 'exponent,' indicating repeated multiplication.
Key Difference
'Index' is often used in British English, while 'exponent' is more common in American English for mathematical contexts.
Example of index
- The index in the equation x² denotes squaring the variable.
- In algebra, indices simplify repeated multiplication expressions.
