Plug in value of extit{t}: First, let's plug in the value of extit{t} into the expression. So we got extit{t} = 3, and we put it in extit{sqrt(t + 22)}.Calculation: extit{sqrt(3 + 22)}
Add up values: Now we add up 3 and 22 inside the square root.Calculation: 25
Find square root: Then, we find the square root of 25, which is 5.Calculation: 25=5
