Chapter 7: Powers


What is powering? X to the nth power or nth power of x
What is a example of repeated multiplication? x^7 you would do x times itself seven times
Product of powers postulate For any nonnegative bases and nonzero real exponents, or any nonzero bases and integer exponents, b^m X b^n=bm+n
Power of a power postulate For any nonnegative bases and nonzero real exponets, or any nonzero bases and interger exponents, (b^m)^n=bm+n
Zero exponent thereom If b is a nonzero real number, b^0=1
Negative exponent thereom For any postive base b and real exponent n, or any nonzero base b and integer exponent n, b^-n=1/b^n
Annual compound interest thereom Let P be the amount of money invested at an annual interest rate of r compounded annually. Let A be the total amount after t years. Than A=P(1+r)^t
