Q. Determine the value of

y

, if

x

121

\newline

y=\sqrt{x}-2

\newline

Answer:

y=

Substitute x value: Substitute the given value of $x$ into the equation. $\newline$ $y = \sqrt{x} - 2$ $\newline$ $y = \sqrt{121} - 2$
Calculate square root: Calculate the square root of $121$ . $\sqrt{121} = 11$
Subtract to find $y$ : Subtract $2$ from the square root of $121$ to find the value of $y$ .
$y = 11 - 2$
$y = 9$
