please help​

Answer 1

expand form is

(3+m)3

=3×3 +3×m

=9+3m

Answer 2

Answer:

(3+m)3

=3.3.3+m.m.m+3.3.3.m+m.m.m

=27+m3+27m+m3

Step-by-step explanation:

i)At first we will see the form of the algebraic problem which is (a+b)3. ii)Then expand according to the formula which is a3+b3+3a2b+3ab2. iii)Here before doing see what coincides of problem with a and what coincides of problem with b and then put the values the corresponding values in the corresponding parts of the formulae and calculate it and you get the answer.
