The answer is -2a^4+4a^2b^2+5b^2a%
Here is the solution for finding mean mode and median
So we have 0.1777777...
let x=0.1777...
then 100x=17.7777 and 10x=1.7777 upon subtraction of the 10x from 100x you get:
100x-10x=17.777-1.777
90x=16
x=16/90
x=8/45
As far as I can see, it should be 5/10 is parrots which is simplified into 1/2 .
Hope this helps!
