Question

find the value of a and b part​

Answer 1

Answer:

a) -5÷(3/5) ^-2

-5÷(5/3) ^2

-5÷25/9

-5×9/25

p/q= -9/5

b) ((-9/5+(-5/9) )^-1

((-81-25) /45) ^-1

(-106/45) ^-1

( p/q+q/p)^-1= -45/106

Step-by-step explanation:

hope it helps you.

Answer 2

Answer:

a) -45/25= -9/5

b) -45/106

Step-by-step explanation:

(-1/5)^-1 = 1/(-1/5)= -5

(3/5)^-2 = 1/(3/5)^2=25/9

so p/q = (-5)/(25/9) = -45/25= -9/5

b) (-9/5- 5/9)^-1 = 1/ (-9/5- 5/9)

taking lcm

1/(-81-25 )/45 = -45/106
