`nif1/(4l)+1/(5!)+1/(6!)=n/(7!)`

Find n, if n/(6!) = 1/(5!) + 1/(4!)

{:("Quantity A","Quantity B"),((1)/(4)-(1)/(5)+(1)/(6)-(1)/(7)+(1)/(8),(1)/(4)):}

The greatest of the numbers 2^(1/2), 3^(1/3), 4^(1/4), 5^(1/5), 6^(1/6) and 7^(1/7) is

5(1)/(4)+6(2)/(3)+7(1)/(6)=?

(1)/(2)((1)/(5)+(1)/(7))-(1)/(4)((1)/(5^(2))+(1)/(7^(2)))+(1)/(6)((1)/(5^(3))+(1)/(7^(3)))-….oo=

(1)/(2)((1)/(5)+(1)/(7))-(1)/(4)((1)/(5^(2))+(1)/(7^(2)))+(1)/(6)((1)/(5^(3))+(1)/(7^(3)))-….oo=
