Question

Find the cube root of 25acube + 54a square b + 3ab square + 8bcube

Answer 1

Answer:

it is an imperfect cube

Step-by-step explanation:

let

cube root of (25a³+54a²b+3ab²+8b³) = ax+by

or,

25a³+54a²b+3ab²+8b² = (ax+by)³

= a³x³+3a²byx²+3ab²y²x+b³y³

By comparison,

y³ = 8, y=2 and y² = 1 , y=1

The values of x and y are not always coming up the same.
