Question

Expand (2x+5y)^3
Who answer the question I will followthem

Answer 1

Answer:

I am sure about the answer.

Step-by-step explanation:

(2x-5y)^3 =

(2x)^3 - 3(2x)^2)(5y) + 3(2x)(5y)^2 - (5y)^3

= 8x^3 - 60x^2y + 150xy^2 - 125y^3

Answer 2

Answer:

8x^3+125y^3+60x^y+150xy^2

Step-by-step explanation:

Given (2x+5y)^3

It is in the form of (a+b)^3 =  a^3+b^3+3ab(a+b)

Here,

a=2x

b=5y

substitute in the above formula ,

(2x)^3 +(5y)^3+3(2x)(5y)(2x+5y)

= 8x^3 + 125y^3 + 30xy(2x+5y)

= 8x^3+125y^3+60x^y+150xy^2
