Answer 1

Answer:

a) a+[3b-5a-{2a-(5a-5b)}]

= a+[3b-5a-{2a-5a+5b}]

= a+[3b-5a-2a+5a-5b]

= a+[-2b-2a]

= a-2b-2a

= a-2b (Ans)

b) 4x-[4y-{x-(2z-2y)+3z-(x-2y-z)}]

= 4x-[4y-{x-2z+2y+3z-x+2y+z}]

= 4x-[4y-x+2z-2y-3z+x-2y-z]

= 4x-4y+x-2z+2y+3z-x+2y+z

= 4x+z(Ans)

c) pq(p-q)+p^2(p^2-q^2)

= p^2q-pq^2+p^4-p^2q^2

= p^2q-pq^2+p^2-p^2q^2(Ans)

I have tried my best to solve these sums for you...hope it helps
