Study Notes
Exponent Laws
Product of Powers
- Law:
a^m × a^n = a^(m+n)
- When multiplying two exponential expressions with the same base, add the exponents
Power of a Power
- Law:
(a^m)^n = a^(mn)
- When raising an exponential expression to a power, multiply the exponents
Power of a Product
- Law:
(ab)^m = a^m × b^m
- When raising a product of two bases to a power, raise each base to that power and multiply
Quotient of Powers
- Law:
a^m ÷ a^n = a^(m-n)
- When dividing two exponential expressions with the same base, subtract the exponents
Zero Exponent
- Law:
a^0 = 1
- Any base raised to the power of 0 is equal to 1
Negative Exponent
- Law:
a^(-n) = 1/a^n
- A negative exponent is equivalent to the reciprocal of the positive exponent
