Square both sides to get rid of the square root

y+8 = 25

solve for y

y = 25-8

y = 17

Reading as:-
â(y + 8) = 5
y + 8 = 25
y = 17

understanding the question as
sqrt(y+8)=5
square on both sides, therefore
y+8=(5)^2
y+8=25
y=25-8
y=17

if the question is
sqrt(y)+8=5
sqrt(y)=5-8
sqrt(y)=-3
square on both sides, therefore
y =9
