Question

Expand (4p+ 5q)³
plz do it​

Answer 1

Answer:

64p³+240p²q+300pq²+125q³

Step-by-step explanation:

(a+b)³ = a³+3a²b+3ab²+b³

(a+b)³ = a³+b³+3ab(a+b)

According to the above formulae,

(4p+5q)³ = (4p)³+3×(4p)²×(5q)+3×(4p)×(5q)²+(5q)³

=> 64p³+240p²q+300pq²+125q³

Here you go!!!

Hope you understand the answer!!
