Super confused on this one! somebody quickly!

The correct answer is A.

Exponents should be multiplied when the expression is in the form (x^a)^b. In this case, the result is always equal to x^(a*b).

For B and D, the exponents should be added since the base is the same. Exponents in C should be subtracted since they are divided and cancel each other out

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.
