Answer 1

Answer:

-4/5 is in the bracket and there is -2 as the exponent. so you have to open the first bracket, so when you will open the first bracket the ratio will be the opposite side and the sign will change. it will be 5/4 and it will be multiplied by 2 in both the denominator and the numerator. so it will be 25(5* 5)/16(4*4). now we have 2 as our exponent. since there is no - sign  why it will simply get multiplied with the numerator and the denominator so the final answer will be

625/736.

i hope this answer will help you...
