Answer 1

Answers:

(a) 3^(-1) + 4^(-1) = 1/3 + 1/4 = 7/12

(b) (3^-1 + 4^-1 + 5^-1)^0 = 1 [Any number to the power 0 is equal to 1]

(c) [1/3^(-1) - 1/4^(-1)]^(-1) = [3 - 4]^(-1) = [-1]^(-1) = -1

Answer 2

Answer:

3^-1 + 4^-1 = 7/12

( 3^-1 + 4^-1 + 5^-1 )^0 = 1

[ { (1/3)^-1 } - { ( 1/4 )^-1} ]^-1 = -1
