Question

Simplify m3 + m3

And

Simplify 10+3c+5d-7c+d

Answer 1

For this case we must simplify the following expressions:

`m ^ 3 + m ^ 3\\10 + 3c + 5d-7c + d`

Expression 1:

`m ^ 3 + m ^ 3 =`

They are similar terms so we can add.

`2m ^ 3`

Expression 2:

`10 + 3c + 5d-7c + d =`

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

`10 + 3c-7c + 5d + d =\\10-4c + 6d`

Answer:

`m ^ 3 + m ^ 3 = 2m ^ 3\\10 + 3c + 5d-7c + d = 10-4c + 6d`
