Question

Factorise 27 y3 + 125 z​

Answer 1

Answer:

it should be 125z3

Step-by-step explanation:

(3y)^3+(5z)^3

(3y+5z)(9y^2-15yz+25z^2)

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

Answer 2

Answer:

Hey mate! Your answer is -

(3)^3y + (5)^3 z

= put the formula of a^3 + b^3= (a+b)(a^2-ab+b^2)

=where a= 3y, b=5z

=(3y+5z) [ (3y)^2 - 3y×5z + (5z)^2

=(3y+5z) [9y^2 - 15 yz + 25z^2]
