Answer 1

Step-by-step explanation:

to make power +ve we can write 1/(x÷y)¹ also 1/(x)¹ and 1/(y)¹

substitute the values

1/7/11÷-22/21 on left hand side

1/7/11= 11/7; 1/-22/21= 21/-22; 11/7/21/22= 11*22/7*21

similarly check right hand side

1/7/11= 11/7

1/-22/21= 21/-22

1/x÷1/y= 11/7÷21/-22

11*22/7*21

both the sides the answer is same. so it is true
