where a is the first term and, d is the common difference of the arithmetic sequence The terms of the arithmetic sequence are computed as per the given formula- an=a+(n−1)d where an is the nth term of the given arithmetic...
As per the law, to divide two exponential expression with the same base we subtract the exponents. It is given as: aman = am– n, where m and n are real numbers and a is a non-zero term. Law of negative exponent The negative exponent rule states that when an exponent is negative...
