a^m × a^n=(a)^m+n a^m ÷ a^n=(a)^m-n a^m × b^m=(a×b)^m (a^m)^n=(a)^m×n (a/b)^m=a^m/b^m (a)^-m=1/(a)^m a^0=1

Rule 1: When the numbers having the same base are multiplied, add the exponents.

a^p × a^q = a^(p+q)

a = base : p,q = exponents

Rule 2: When the numbers having the same base are divided, subtract the exponents.

a^p ÷ a^q = a^{(p-q)} i.e. a = base: p,q = exponents

Rule 3: Multiply the powers when the numbers are raised by another number.

(a^p)^q= a^{(pxq)} =a^{(pq)}
