The algebric expression of substrabing 4x from the square root of y is?

1.
`\tt √(y) - 4x`

2.
`\tt4x - √(y)`

3.
`\tt {y}^(2) - 4x`

4.
`\tt4x - {y}^(2)`

`\large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}`

• Here, we have the keyword ⇨ subtracting 4x from the square root of y.
• Since, there's the word 'from', we must put the square root of y first, then add the minus symbol since the operation given is subtraction & lastly, we should add 4x.
• This is how you write the square root of y
  `\downarrow`
• 
  `\large \tt √(y)`
• The last 2 options show y² (y to the power of 2 / y square).... it's not the square root of y. So, we can eliminate the last 2 options.
• Now, let's identify the correct answer from the 1st 2 options. I already explained that the square root of y should come first, so the correct answer is Option 1.
  `\boxed{\boxed{\bf √(y) - 4x}}`
