I'm not sure how to write a radical sign on the computer but the problem is y+3-4=5 inside a radical sign.

try √ to copy/paste.

as written, I read

y+3-4 = √5

but that seems unlikely.

You can also write sqrt(...) to show explicitly what is inside the radical.

Steve, no the sqrt(...) is over the y+3 not over the 5

so, if you have

√(y+3) - 4 = 5
√(y+3) = 9
y+3 = 81
y = 78

by the way, I meant that you could have written sqrt(y+3), not just show ... as the argument.

To write a radical sign on a computer, you can use the square root symbol (√). Here's how you can write the problem "√(y + 3 - 4) = 5":

1. Open a word processing software or any text editor where you want to write the problem.

2. Place the cursor where you want to insert the radical sign.

3. Depending on the program, you can use one of the following methods:
- Method 1: In most word processors, you can go to the "Insert" tab or menu and select "Symbol" or "Special Characters." Look for the square root (√) symbol and insert it into the document at the desired location.
- Method 2: On a Windows computer, you can use the Alt code by pressing and holding the Alt key while typing "251" on the numeric keypad. Release the Alt key to insert the square root symbol (√).
- Method 3: If you are using a language or math software like LaTeX or MathType, you can use the appropriate syntax to insert the radical sign.

Now that you know how to write the radical sign, let's solve the equation:

√(y + 3 - 4) = 5

To solve this equation, we need to isolate the variable "y" by performing the necessary operations step by step:

1. Simplify the expression inside the radical sign:
y + 3 - 4 = y - 1

2. Square both sides of the equation to remove the radical sign:
(y - 1)^2 = 5^2
(y - 1)^2 = 25

3. Expand the left side by applying the square:
y^2 - 2y + 1 = 25

4. Move the constant term to the right side:
y^2 - 2y + 1 - 25 = 0
y^2 - 2y - 24 = 0

Now, you can continue solving the quadratic equation.
