Question

3 x cube Y - 243 x y cube​

Answer 1

Answer:

3x^3y-243xy^3

ans-3xy • ( x+9y ) • ( x-9y )

Step-by-step explanation:

step 1 -

equation at the end of first step.

( (x • (x^3) ) •y) - 3^5 xy^3

step 2-

equation at the end of step 2-

(3x^3 • y) - 3^5xy^3

PULL OUT LIKE TERMS -

3x^3y-243xy^3=3xy •(x2-81y2)

factories x2-81y2 -

=81 is the square of 9.

= x2 is the square of x

=y2 is the square of y

Factorisation is-( x+9y ) ( x-9y )

final result-

3xy•(x+9y)•(x-9y)

Answer 2

Answer:

3xy(x^2-81y^2)

3xy[x^2-(9y)^2)

3xy(x-9y)(x+9y)
