Is 7x7x7=28because we are learning prime factorsi really don't get itlike ,is 2x2x2x2=16i just want you to give me the answerfor 7x7x7

To make it easier, you must break it down. you already know that 7x7 equals to 49. now, you multiply 49 with another seven. so it should look like this:

(7x7)7 (you do the parenthesis first)

=49x7
=343, so that statement 7x7x7=28 would be false.
