Prajwalitapal044: Besides, how can you assume x =2 & y= 4

Answered by Prajwalitapal044

b. 8x^3+27y^3

=(2x)^3+(3y)^3

Applying the formula of a^3+b^3

=(2x+3y)^3-3xy(2x+3y)

=(14)^3-3(8)(14)

=2744-336

=2408

d. 27a^3+8b^3

=(3a)^3+(2b)^3

Applying the formula of a^3+b^3

=(3a+2b)^3-3ab(3a+2b)

= 6^3-3(2)(6)

=216-36

= 180

Hope this helps
