81 = (-3)^4

-81 = -3^4

1/81 = 3^-4  because 3^-4 = 1 / 3^4 = 1 / 81

- 1/81 = -3^-4 because  -3^-4 = -1 /(3^4) = - 1 / 81

Lily said that n=3 is a solution of the equation 16+n=18.Is Lily correct ?Explain
MAVERICK [17]
No, Lily is not correct. This is because 16+3 does not equal 18. So to find N, you take 18 and subtract 16. 
18-16=n 
18-16=2
so n=2
16+2=18.
