Question

please tell me the Right correct answers please ... For class 8 ​

Answer 1

Answer:

(-9/5)^-99

and

1/8

Step-by-step explanation:

multiplicative inverse is

x * 1/x=1 or x*(x)^-1=1

where multiplicative inverse of x is (x)^-1

Now

(-5/9)^-99=1/(-5/9)^99=(-9/5)^99=x

inverse is x^-1=(-9/5)^-99

second question

(1/4)^-1+(1/2)^-2=4+4=8

now inverse of 8 is (1/8)
