Question

(3^-1+4^-1)*(7/12)^-1​

Answer 1

Answer:

1

Step-by-step explanation:

(3^-1+4^-1)*(7/12)^-1​ = [1/3 + 1/4] x [12/7]

                              = [(4 + 3)/(4 x 3)] x [12/7]

                              = 7 / 12 x 12 / 7

                              = 84/84

(3^-1+4^-1)*(7/12)^-1​ = 1  

Hope this helps! :)
