Long Answer:

You must multiply each number/variable inside the parentheses by the number outside to get rid of the parentheses and simplify the expression. In other words, you must use the distributive property.

In this case, you would multiply 5 by 3 to get 15 and m by 3 to get 3m. Keep in mind that you must multiply EVERY number/variable within the parentheses by the number outside.

Your new, simplified expression will be 15•3m.

Short Answer:

Get rid of the parentheses by multiplying (5•m) by 3 to get 15•3m.

(5*m)*3 is the same as 3(5*m)

Distribute the 3 to each term giving you 15*3m. Depending on the format of the teach she would either want 15*3m or 3(5*m).

You have to use the distributive property.

5*3=15 and m*3=3m

So your answer is 15*3m

If that mark means multiply, you just need to multiply the outside by the inside. So it would be 15m
