|properties of powers ||product of powers postulate, power of a power postulate, power of a product postulate, quotient of a powers postulate, power of a quotient postulate, ngative exponets property|
|graph of y=x^n ||if n is even parabola with refletion symmetry if n is odd rotation symmetry|
|Compound interest formulas ||Annual: A=P(1+r)^t
|Example: Is -i*square root of 3 a fourth root of 81? ||(i*square root of 3)^4 =9.
no because it does not equal 81.|
|finding negative exponents ||negative exponents are recipricals.
Example: 4^-2 = 1/16|
|explict formulas for geometric sequences ||g sub n= g sub 1(r)^ the previous term |
|Number of real roots ||even root of + # - 2 solutions
odd root of + # - 1 solution
even root of a - # - no solutions
odd root of a - # -1 solution.|
