What is the meaning of a positive exponent?

A positive exponent indicates how many times a number should be multiplied by itself. For example, in the expression 2^3, the positive exponent 3 means that 2 should be multiplied by itself three times: 2 * 2 * 2, which equals 8. Positive exponents result in larger values as they represent repeated multiplication.

What is the meaning of a negative exponent?

A negative exponent represents the reciprocal of the base raised to the positive value of the exponent. In other words, if a number is raised to a negative exponent, it means that you divide 1 by the base raised to the positive value of the exponent. This indicates that the result will be a fraction or a decimal value, depending on the base number.

How do you simplify a number with a positive exponent?

To simplify a number with a positive exponent, you need to raise the base number to the power of the exponent. For example, if you have 5^3, you would multiply 5 by itself three times (5 x 5 x 5) to get 125. This is the simplified form of the number with a positive exponent.

How do you simplify a number with a negative exponent?

To simplify a number with a negative exponent, you can move the base with the negative exponent to the denominator of a fraction and change the sign of the exponent to positive. For example, if you have 2^-3, you can rewrite it as 1/(2^3) which simplifies to 1/8.

Give an example of a number raised to a positive exponent.

An example of a number raised to a positive exponent is 2^3, which is equal to 2 multiplied by itself 3 times, resulting in 8.

Give an example of a number raised to a negative exponent.

An example of a number raised to a negative exponent is 5^-2, which is equivalent to 1/5^2 or 1/25.

What is the rule for dividing numbers with positive exponents?

When dividing numbers with positive exponents, you subtract the exponents of the same base. For example, when dividing x^3 by x^2, you subtract 2 from 3 to get x^1, which simplifies to x. So the rule for dividing numbers with positive exponents is to subtract the exponents when dividing numbers with the same base.

What is the rule for dividing numbers with negative exponents?

When dividing numbers with negative exponents, you can rewrite the expression by moving the term with the negative exponent to the denominator and changing the sign of the exponent to positive. This means that if you have a fraction where the exponent of the denominator is negative, you can move it to the numerator and change the sign of the exponent to positive. For example, if you have 3^-2/5^3, you can rewrite it as 5^3/3^2.

Give an example of simplifying a fraction with negative exponents.

An example of simplifying a fraction with negative exponents is \( \frac{1}{x^{-2}} \). By moving the \( x^{-2} \) from the denominator to the numerator and changing the sign of the exponent to positive, the fraction simplifies to \( x^{2} \), making it easier to work with and understand in calculations.

How do you determine the value of a number with a negative exponent?

To determine the value of a number with a negative exponent, you can take the reciprocal of the base raised to the positive version of the exponent. For example, if you have a number like 3^-2, you would calculate it as 1 / (3^2), which equals 1/9. This process essentially moves the base with the negative exponent to the denominator in the form of its positive exponent.
