" Bvaluate ":{((1)/(3))^(-1)-((1)/(4))^(-1)}^(-1)

{(3/4)^(-1)-(1/4)^(-1)}^(-1)

The value of [(1)/(3)]^(-1)-((1)/(4))^(-7)}+[((1)/(4))^(-1)-((1)/(5))^(-1)]+[((1)/(5))^(-1)-((1)/(6))^(-1)]^(2)] is

(3^(-1)-:4^(-1))^(-1)

Evaluate : 1{(1/3)^-1-(1/4)^-1}^-1

(3)^(-1)+(6)^(-1)-:(3/4)^(-1)

(4^(-1)-3^(-1))^(-1)+(2^(-1)-3^(-1))^(-1)=((1)/(4)-(1)/(3))^(-1)+((1)/(2)-(1)/(3))^(-1)
