Answer:
B, E, F
Step-by-step explanation:
Equivalent expressions are expressions which are equal. To show expressions are equal, reduce to lowest terms by simplifying using exponent rules.
A. 8^2*8^x = 8^2+x
B. (8*8)^x = 64^x
C. 8*8^2x = 8^(2x +1)
D. 8*8^x = 8 ^ (x+1)
E. 8^2x = 64^x
F. 8^x*8^x = 8^(x+x) = 8^(2x) = 64^x
