Question

Find the reciprocal of the following exponential form: (3)^20/(3)^8​

Answer 1

Step-by-step explanation:

3^20 ÷ 3^8

now here the base is same and division sign is used we can subtract the exponents

= 3^(20-8)

=3^12

now reciprocal of this will be 1÷ the number

= 1/3^12

= 3^(-12).

negative exponents means you have to change the base from denominator to numerator or numerator to numerator.
