pls just give me answer its not 128 In how many ways can you put seven marbles in different colors into four jars? Note that the jars may be empty.

840 ways.

Step-by-step explanation:

For the first jar, you have 7 marbles to put in.

For the second, you now have 6 marbles to put in.

For the third, you have 5 marbles.

For the fourth, you have 4 marbles.

7 * 6 * 5 * 4

= 42 * 20

= 840 ways.

Hope this helps!

2nd one in the first row is correct
