Question

Find the value of
a) 8xyz x (xyz - 2x²y?y?) for x = 1, y = 3,2 = 2.
b) p² x (7pq - 8r) for p = 1,9 = 1, r = 1.
plz someone help me to solve
this problem... who will answer I will mark as brainlist ​

Answer 1

Answer:

a. (8xyz + xyz) + (-2 + 2x) + (y + y)

= 9xyz + 0x + (3 + 3)

= 9xyz + 6

Therfore the ans of a) is = 9xyz + 6

b. p×p + (7pq - 8r)

= 1 + 7-8

= 1 + (-1)

= 1 - 1

= 0

Therefore the ans of b) is = 0
