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 General: A=p(1+r/n)^n*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
