How do you simplify #2^-4#? Prealgebra Exponents, Radicals and Scientific Notation Exponents 1 Answer Shwetank Mauria Jun 29, 2016 #2^(-4)=1/16# Explanation: As #a^m-:a^n=a^(m-n)#, if #m=0#, we have #a^0-:a^n=a^(0-n)# or #1/a^n=a^(-n)# i.e. #a^(-n)=1/a^n# Hence, #2^(-4)=1/2^4=1/(2xx2xx2xx2)=1/16# Answer link Related questions How do you simplify #c^3v^9c^-1c^0#?
