Question

If y raise to power 2 + 18 is equal to 27 what is the positive value of y
​

Answer 1

If y^2 + 18 = 27, we can solve for y as follows:

y^2 + 18 = 27

Subtracting 18 from both sides, we get:

y^2 = 9

Taking the square root of both sides, we get:

y = ±3

Since we are looking for the positive value of y, we can discard the negative solution and conclude that the positive value of y is:

y = 3.

Answer 2

y = 3

Explanation:

Given the equation:

`y^2 + 18 = 27`

We can solve for y by:

• subtracting 18 from both sides, then
• taking the square root of both sides

`\begin{aligned}y^2 + 18 &= 27 \\ \underline{-18} &\text{} \ \ \ \ \underline{-18}\\ √(y^2) &= √(9) \\ y &= \pm3\end{aligned}`

Finally, we can take only the positive value of y, which answers the question.

`y= 3`
