Exponent Pretest

Front

What is the rule for rewriting negative exponents?

Back

A negative exponent indicates that the base should be taken as the reciprocal. For example, w^-n = 1/w^n.

Front

How do you express repeated multiplication using exponents?

Back

Repeated multiplication of the same number can be expressed as that number raised to the power of the number of times it is multiplied. For example, 2 x 2 x 2 x 2 = 2^4.

Front

What happens to the exponents when you multiply powers with the same base?

Back

When multiplying powers with the same base, you add the exponents. For example, a^m * a^n = a^(m+n).

Front

What is an exponent in a mathematical expression?

Back

An exponent indicates how many times the base is multiplied by itself. For example, in 8^4, the exponent is 4.

Front

What happens to the exponents when you divide powers with the same base?

Back

When dividing powers with the same base, you subtract the exponents. For example, a^m / a^n = a^(m-n).

Front

What is the value of any non-zero number raised to the power of zero?

Back

Any non-zero number raised to the power of zero equals 1. For example, 5^0 = 1.

Front

What is the product of powers rule?

Back

The product of powers rule states that when multiplying two powers with the same base, you add the exponents.

Front

What is the quotient of powers rule?

Back

The quotient of powers rule states that when dividing two powers with the same base, you subtract the exponents.

Front

How do you express a power raised to another power?

Back

When raising a power to another power, you multiply the exponents. For example, (a^m)^n = a^(m*n).

Front

What is the power of a product rule?

Back

The power of a product rule states that when raising a product to a power, you can distribute the exponent to each factor. For example, (ab)^n = a^n * b^n.
