What expression using a base and exponent?

An expression using a base and exponent takes the form ( a^n ), where ( a ) is the base and ( n ) is the exponent. The base represents a number that is multiplied by itself, while the exponent indicates how many times the base is used in the multiplication. For example, in the expression ( 2^3 ), 2 is the base and 3 is the exponent, meaning ( 2 \times 2 \times 2 = 8 ).


What is the exponent of 2 times 2?

The expression "2 times 2" equals 4. In terms of exponents, 4 can be expressed as (2^2). Therefore, the exponent of 2 in this context is 2.

How do you evaluate each expression with only one exponent?

To evaluate an expression with only one exponent, first identify the base and the exponent. Then, apply the exponent to the base by multiplying the base by itself as many times as indicated by the exponent. For example, to evaluate (2^3), you would calculate (2 \times 2 \times 2), which equals 8. Finally, if the exponent is negative or a fraction, adjust your calculation accordingly, such as using the reciprocal for negative exponents.


What is an expression using a base and a exponent?

An expression using a base and an exponent is a mathematical representation where a number (the base) is raised to a power (the exponent), indicating how many times the base is multiplied by itself. For example, in the expression (2^3), 2 is the base and 3 is the exponent, which means (2 \times 2 \times 2 = 8). This notation is commonly used in algebra and various fields of mathematics.


What is the multiple expressed by an exponent?

An exponent indicates how many times a number (base) should be multiplied by itself. For example, 2^3 means 2 x 2 x 2, which equals 8. So, the multiple expressed by an exponent is the result of multiplying the base number by itself the number of times specified by the exponent.

A number that shows how many times the base is used as a factor is the - what?

Exponent. For example: in 25 (which can also be written 2^5), 5 is the exponent and means that the 2 is multiplied 5 times (or 2*2*2*2*2).


How do you use an exponent?

its shows how many times you multiply a number to its self.. if you got 2 exponent 5..it means you have to multiply 2, 5 times to itself.. 2x2x2x2x2=32
