In this program we will see how to find nth power of a number.

Write 8085 Assembly language program to find nth power of a number. The base is stored at location 8000H, and the exponent is stored at 8001H. Store the result at 8002H.

In 8085, we cannot perform the multiplication operation directly. Here we are writing a subroutine to perform the multiplication by using repetitive addition. To perform nth power of a number, we have to multiply the number n times. The n value is used as a counter. If the base is 03H, exponent is 05H, then the result is F3H (243D)
