Q. Determine the value of

y

, if

x

is

16

.

\newline

y=\sqrt{x}-4

\newline

Answer:

y=

Substitute $x$ value: Substitute the value of $x$ into the equation. $\newline$ We are given that $x = 16$ , and we need to find the value of $y$ from the equation $y = \sqrt{x} - 4$ . $\newline$ Substitute $x$ with $16$ : $y = \sqrt{16} - 4$ .
Calculate square root: Calculate the square root of $16$ . The square root of $16$ is $4$ , since $4 \times 4 = 16$ . So, $y = 4 - 4$ .
Subtract to find $y$ : Subtract $4$ from $4$ to find the value of $y$ . Perform the subtraction: $y = 4 - 4 = 0$ .
