The algebric expression of substrabing 4x from the square root of y is?
1. [tex]\tt \sqrt{y} - 4x[/tex]
2. [tex]\tt4x - \sqrt{y} [/tex]
3. [tex]\tt {y}^{2} - 4x[/tex]
4. [tex]\tt4x - {y}^{2} [/tex]
[tex] \large \boxed{\mathbb{ANSWER\: WITH\: EXPLANATION} \downarrow}[/tex]
- 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 [tex]\downarrow[/tex]
- [tex] \large \tt \sqrt{y} [/tex]
- 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. [tex]\boxed{\boxed{\bf \sqrt{y} - 4x}}[/tex]
