Exponent Rules (Simple Laws of Exponents)

What is the product rule for exponents?

• When multiplying like bases, subtract the exponents: a^m × a^n = a^(m-n).

• When multiplying like bases, add the exponents: a^m × a^n = a^(m+n).

• When multiplying like bases, multiply the exponents: a^m × a^n = a^(m*n).

• When multiplying like bases, divide the exponents: a^m × a^n = a^(m/n).

What is the power of a power rule?

• When raising a power to another power, add the exponents: (a^m)^(n) = a^(m+n).

• When raising a power to another power, multiply the exponents: (a^m)^(n) = a^(m*n).

• When raising a power to another power, subtract the exponents: (a^m)^(n) = a^(m-n).

• When raising a power to another power, divide the exponents: (a^m)^(n) = a^(m/n).

What is the zero exponent rule?

• Any non-zero base raised to the power of zero equals one: a^0 = 1.

• Any number raised to the power of zero equals zero: a^0 = 0.

• Any non-zero base raised to the power of one equals zero: a^1 = 0.

• Any number raised to the power of zero equals one: a^0 = 1.

What is the negative exponent rule?

• A negative exponent indicates the reciprocal: a^{-n} = 1/a^n.

• A negative exponent means the base is negative.

• A negative exponent indicates that the number is less than one.

• A negative exponent means to multiply the base by itself.
