Can you please assist with the induction step for this problem?
3. Prove that
1 + 2 + 2^2 + ... + 2^(n-1) = 2^n - 1
for every n > 1.
5. Prove that for any real number x and for all numbers n > 1,
x^n - 1 = (x - 1)(x^(n-1) + x^(n-2) + ... + x^(n-r) + ... + x + 1).© BrainMass Inc. brainmass.com October 10, 2019, 5:59 am ad1c9bdddf
