If you could show a picture of the clocks I could help you
N^2 y^2
n squared and y squared
I think it’s the second one b
I hope this helps :)
Ok so 1st, you do the (80 ÷ 20), then you get
10-4+(4)y^4
then you 10-4
6+(4)y^4
then....
(10)y^4
so then it's
10y^4
Unless there is a =, but if not it's 10y^4
