please solve these questions-(1) 8x^2y^2-16xy+8 (2) 25x^2-2x+1/25 (3) x^3-3x^2+3x-1 (4) x^3/8-x^2/4+x/6-1/27​

Answer 1

5n(2n3+n2+8)+n(4-n).

= 5n × 2n3 + 5n × n2 + 5n × 8 + n × 4 - n × n.

= 10n4 + 5n3 + 40n + 4n – n2.

= 10n4 + 5n3 + 44n – n2.

= 10n4 + 5n3 – n2 + 44n.

Answer: 10n4 + 5n3 – n2 + 44n
