In mathematics, exponentiation is an operation involving two numbers: the base and the exponent or power. Exponentiation is written as b n, where b is the base and n is the power; this is pronounced as "b (raised) to the (power of) n ".

- Yes, it's like this: _4.8 = 4 4/5 = 24/5. So it's 5 √5 to the power of 24_. *So the answer is 1*.
- leilaizarte, when you have a positive exponent, you are multiplying the base number by itself for as many times as the exponent indicates. For exam...
- yes you are correct
- Do you mind specifying? I can't really understand your question.
- press the^ arrow or (shift)_6
- Its just another name for exponents for example 4^4 is said as four to the fourth power.
- 9^33 is going to be larger. Try it in a calculator :o Exponentiation is not like multiplication in that you can swap the numbers and get the same a...
- *1.558006e+57* thats the answer to your question!
- You can do any number except 0 to a negative power. The reason is that 0 to a negative power would be division by 0 which is undefined.

Exponentiation is a process or operation of taking the exponent of a number. If x is an integer raised to n which is a positive integer, then it can be expressed as x^n. Learn more about exponentiation in this article.
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".
Exponentiation is a way of shortening the process/equation of repeatedly multiplying many copies of a number. An exponent 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.
