Answer 1

Answer:

Given :

Given :• p = - 1

Given :• p = - 1• q = -3

Given :• p = - 1• q = -3• r = 7

Given :• p = - 1• q = -3• r = 7To Find:

Given :• p = - 1• q = -3• r = 7To Find:pº + pqr - pr

Given :• p = - 1• q = -3• r = 7To Find:pº + pqr - prAnswer:

Given :• p = - 1• q = -3• r = 7To Find:pº + pqr - prAnswer:3 •p³ + pqr - pr
