State True or False : (i) For any non-zero number a, we have (am)n = am+n. (ii) If a and b are non-zero numbers, then (iii) For a non-zero number x; (xm x xn) is equal to x to the power (m + n). (iv) If a number p is multiplied n times, then the resulting number is pn. (v) In an exponential notation xn; n is called the index.
