Question

if a/ b = [ -2 / 3 ] -3 ÷ [ 4/3] -4 find the value of:
1- [ a/ b] -1
(ii)- [ a/ b + b/ a ] -1


​

Answer 1

a/b =( - 2 /3 )÷ - 3 ÷ 4/3× - 4

a / b = - 2 /3× 1 / - 3÷ 4 / 3 × 1/-4 -------- ( reciprocal of -3 is 1/ -3 )

a/ b = (2/9 ) ÷ 16 / 9

a/b = 2/ 9 × 16 /9 -------( reciprocal of 16 /9 is 9 /16 )

a / b = 8

1. 1 -[ a/ b ] -1

ans : 1 - 8 - 1

- 7- 1= - 8

2. - [ a / b + b / a ] -1

- 8 - 1 / 8- 1

- 17 /8
