**Q: **Is a exponentiation used extensively in many fields? ¶

**A: **Yes, and including economics, biology, chemistry, physics, and computer science, with applications such as compound interest, population growth, chemical reaction kinetics, wave behavior, and public-key cryptography.

**Q: **Is a exponentiation not commutative? ¶

**A: **Yes.

**Q: **Is an exponentiation computationally inexpensive in finite fields? ¶

**A: **Yes, and whereas the discrete logarithm is computationally expensive.

**Q: **Is an exponentiation considered as a multivalued function then the possible values of 1/2 are {1, −1}? ¶

**A: **Yes, The identity holds but saying {1} = { 1/2} is wrong.

**Q: **Is an exponentiation repeated multiplication" can be reinterpreted as "multiplication is repeated addition""? ¶

**A: **Yes, Thus, each of the laws of exponentiation above has an analogue among laws of multiplication.

**Q: **Is a exponentiation not associative either? ¶

**A: **Yes.
