exponential notation	A shorter way to write repeated multiplication. For example, 2⁴ means 2 • 2 • 2 • 2. Two is used as a factor 4 times.
power rule for exponents	To raise a power to a power, multiply the exponents. (x^a)^b = x^a^•^b
product rule for exponents	To multiply two exponential terms with the same base, add their exponents. (x^a)(x^b) = x^a^+b
quotient rule for exponents	For any non-zero number x and any integers a and b:
