My answers are the last one in each number

Answer 1

just plug and chug, using the quotient rule

(2^x ln2 - e^x)(2^x+e^x) - (2^x-e^x)(2^x ln2 + e^x)
-------------------------------------------------------
(2^x+e^x)^2

You can "simplify" that to

Answer 2

just plug and chug, using the quotient rule

(2^x ln2 - e^x)(2^x+e^x) - (2^x-e^x)(2^x ln2 + e^x)
---------------------------------------------------------------
           (2^x+e^x)^2

You can "simplify" that to

Answer 3

(2^x ln2 - e^x)(2^x+e^x) - (2^x-e^x)(2^x ln2 + e^x)
---------------------------------------------------------------
(2^x+e^x)^2
