1) Rewrite the given expression in the form of t^B where B is simplified as much as possible: [t^3-n t^7n]/[(t^2)^n]
[HR][/HR]2) Simplify completely as a fraction in factored form: 15c-3c^2/c^2-c-20
[HR][/HR]3)What values of x make the expression sqr(x+3)/x-2 undefined? Express your final answer using interval notation.
