Question

X + Y to the power -1 and X to the power -1 + Y to the power minus 1
for X equal to 3 by 4 and Y is equal to minus 9 by 8 insert a rational number between​

Answer 1

Answer:

(x+y)^-1------(eq-1)

x^-1+y^-1-------(eq-2)

x=3/4

y=-9/8

Putting the values in eq-2

=(3/4)^-1+(-9/8)^-1

=(4/3)+(-8/9)

=12-8/9

=4/9

Putting the value in eq-2

= (3/4+(-9/8)^-1

= (3/4-9/8)^1

= (6-9/8)^-1

= (3/8)^-1

= 8/3

The rational no are 4/9 and 8/3
