Show that e^z(bar) = e^z (bar as whole) 3. Show that ež = ez.
read the example and froof and answer for question 2. Example: Prove Vn EZ with n20, 8 (3-1) Proof: Let P(n) be 8 (3*-1). [Again, using the word "be" since using an equals sign with a divisibility symbol would make no sense.] Since 320-1-0 and 8 0, P(o) is true. Next, let k eZ and k 20 and assume P(k) is true. This means 8|(32-1) so 3 xeZ such that 8x 3-1, or 3 8x+1. Then 32+)-13242 -1 -3 32-1...
