Answer 2

Answer:

a) 64a³ + 48$a^{2}$  - 24a + 1

b) 1190636

Step-by-step explanation:

a) 1 - 64a³

64= 4³ , 1=1³

1³ - (4a)³

= (a-b)³

=a3 - 3a2b + 3ab2 - b3.

= 1 - 24a + 48$a^{2}$ - 64a³

= - 64a³ + 48$a^{2}$  - 24a + 1

b) (106)³​

= (100+6)³​

= 1000000+ 36 + 1800(100+6)

=1000000 + 36 + 180000 + 10600

= 1190636
