Which expression is equivalent to 6^4•6^3?

A. (6•6•6•6)+(6•6•6)

B. (6+6+6+6)•(6+6+6)

C. (6•6•6•6)•(6•6•6)

D. (6•6•6•6•6)•(6•6•6•6)

C.

Step-by-step explanation:

if a number has a exponent, it tells how many times is the number getting multiplied by itself. 6^4 has a 4 and that mean there are 4 "6s"

6^4=6*6*6*6

and then there is 6^3 which has a 3 and that means it has 3 "6s"

6^3=6*6*6

(6•6•6•6)*(6•6•6)
