Prove using induction that 8k 2 N,2kYki=1(2i 1) =(2k)!k!Note the following pieces of notation:Yki=1(2i 1) = 1 3 5 (2k 3) (2k 1)k! = k (k 1) (k 2) 2 1

Need ! give step by step solutions on how to solve number one \frac{9-2\sqrt{3} }{12+\sqrt{3} } number two x+4=\sqrt{13x-20} number three (domain and range) f(x)=2\sqrt[3]{x} +1

What is best way to getting answer for my exam is

How do i simply this expression (quadratic formula basis) on a ti-84 or normal calculator?
