What is an exponent?
An exponent is an number that indicates how many times a base should be multiplied by itself. It is represented above and to the right of the base as a small number.
Example:
In mathematical expression 2 ^{ 3 , number 2 is the base and number 3 is the exponent. This means that we should multiply number 2 by itself 3 times. }
2 ^{ 3 = 2 x 2 x 2 = 8 }
Exponent Properties:
There are some important properties of exponents that facilitate mathematical calculations. Some of them are:
- Multiplication of equal bases: When we have equal bases to different exponents, we can multiply the exponents.
- equal basis division: When we have equal bases to different exponents, we can divide the exponents.
- Power of a power: When we have a high power to an exponent, we can multiply the exponents.
- Powers of the same base: When we have a power product of the same base, we can add the exponents.
- Powers of the same base: When we have a power quotient of the same base, we can subtract the exponents.
Utility of exponents:
exponents are widely used in various areas of mathematics and science. They allow very large or very small numbers to represent more compactly and facilitate calculations involving operations repetitions.
In addition, exponents are also used in exponential equations, which describe the growth or decrease of an amount over time.
Conclusion:
exponents are numbers that indicate how many times a base should be multiplied by itself. They have properties that facilitate mathematical calculations and are widely used in various areas.
