Answer 1

Explanation:

I am not sure what you mean by * as exponent (15*/3*).

so, I am not sure about C.

A is correct : x5 = 5x

B is incorrect : 5.5x^-1 = 5.5×1/x = 5.5/x. this is NOT 5x.

C ?

D is incorrect : 5.5x^+1 = 5.5x. this is NOT 5x.

E is correct : 15x/3 = 5x

F is correct : (15/3)x = 15x/3 = 5x
