Which expression is equivalent to -x4x4x4x4x4x4x4x4?

An expression equivalent to that given would be 4^8 or also written as four to the eighth power, hope this helped! Please rate my answers.

Work: 4^8 = 4x4x4x4x4x4x4x4

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

The answer is c. 7 (i think) i’m almost sure though
