Question

expand (3+m)^3
pls answer I will surely mark you as brainlist ​

Answer 1

Answer:

m³ + 27 + 27 m + 9m²

Step-by-step explanation:

We will use identity for this purpose in our solution.

Identity are like already defined formulas in mathematics that are prepared in terms of variables and can be used to solve cubes and squares of expressions.

( 3 + m )³

Using identity,

=> 3³ + m³ + 3 * 3 * m ( 3 + m )

Performing simply multiplication,

=> 27 + m³ + 9m ( 3 + m )

Performing simple multiplication once again,

=> m³ + 27 + 27 m + 9m²

There you go! That's your answer.

Answer 2

Answer:

27 + 27m + 9m^2 + m^3

Step-by-step explanation:

(3+m)^2 = 3^3 + 3(3)^2(m) + 3(3)(m)^2 + m^3

=27 + 3(9)(m) + 9(m)^2 + m^3

27 + 27m + 9m^2 + m^3

This is your answer
